Trek Marlin vs Trek Roscoe, which Trek hardtail is right for you?

Comparing Trek's two latest hardtail mountain bikes

Katherine Moore

Choosing which bike to buy, whether it’s your very first mountain bike, an exciting upgrade or you’re looking to try something different, is always a task worth taking your time over.

While on the face of it, some bikes may seem similar, when you dig down into the bike’s geometry, frame design, suspension setup and specs, there are often key differences that go hand-in-hand with their intended use.

Take two of Trek’s most popular hardtail mountain bikes : the best-selling Marlin and the more aggressive Roscoe. On the face of it, they look very similar, but understanding the differences will help you work out which is best suited to you.

What type of riding are you doing?

Forget drool-worthy paintjobs, detailed geometry figures and component choices to start with – the most important thing to consider when choosing the best mountain bike for your needs is to align the type of bike with the style of riding that you’re likely to be doing.

Mountain biking is a broad church, after all, covering everything from multi-day cross-country stage races to four-minute downhill runs, and everything in between.

Bikes intended for these different mountain biking disciplines are designed accordingly; cross-country bikes are best for pedalling and downhill bikes are best for descending. Those in between, including downcountry bikes , trail bikes and enduro bikes , are typically built to balance pedalling efficiency and trail capability on a sliding scale between them.

The Trek Marlin is a beginner-focused hardtail that sits at the cross-country end of the mountain biking spectrum, with a 100mm short-travel suspension fork.

However, the third-generation Marlin has been updated with a number of features that make it both more trail-friendly and upgradeable.

Cleverly, the Marlin also boasts some additional mounts that make it a versatile choice beyond mountain biking, with the capability to fit a kickstand, pannier rack and bags. This enables it to double up as a rugged tourer or urban commuter for cycling to work .

With a greater level of suspension on offer (140mm on most models), more trail-focused geometry, mountain-bike specific frame features and larger tyres, the Trek Roscoe, on the other hand, is a dedicated trail hardtail built for more rugged terrain.

Both the Marlin and Roscoe are alloy hardtails, which helps to keep the prices towards the budget end of the spectrum. Expect to pay more for a lighter carbon fibre frame if you cast your eye at the Procaliber family, designed with fast-paced cross-country racing in mind.

We’ll take a look at the specific features of the Marlin and Roscoe in turn. Key to weighing up which of these hardtails is best for you is deciding what you want to do with it, whether you’re looking to push yourself on challenging trails or are looking for something that’ll help you get about town just as easily as it takes on a local off-road loop.

Because the frame design is so key to how bikes feel to ride, geometry is a good place to start when comparing bikes. You can read BikeRadar’s full guide to mountain bike geometry for more; we’ll focus on the key numbers when comparing the Trek Marlin and Trek Roscoe here.

In terms of head tube angles, while the Marlin’s geometry, updated on the newest third-generation models, has recently been slackened to 66.5 degrees, the Roscoe hardtail is designed around an even slacker 65-degree angle.

Essentially, the slacker the head tube angle, the further forward the front wheel is placed in front of you, and the more capable the bike becomes over rougher terrain.

In combination with the greater level of suspension travel, the slacker head tube angle of the Roscoe means you have to shift your weight further forwards on the bike to weight the front wheel. This results in a more aggressive riding position compared to the more upright position of the Marlin.

Seat tube angles are similar across the Marlin and Roscoe, at 73.4 and 73.1 degrees respectively, steepened to enhance pedalling efficiency for flatter gradients, pedal ups and linking sections of trail.

Both the Roscoe and Marlin offer a wide range of frame sizes, including Trek’s extra size option sitting between medium and large. However, it’s the Marlin that can accommodate the widest range of riders, catering for teens as well as adults with the XXS option.

Another point of difference between these two hardtails is the handlebar width, with the Marlin using 690/720/750mm bars (dependent on frame size), while the Roscoe is fitted with wider 750/780mm handlebars, again for added control on steeper and trickier off-road descents.

With a cross-country-oriented design for efficient pedalling, the Marlin uses a short-travel 100mm fork.

For a more trail-ready ride, the new third-generation Marlin can accept a 120mm-travel fork on all frame sizes from XS up, if you fancy upgrading your ride as you gain confidence and start to tackle larger trail features.

With a hefty 140mm suspension on offer, the Roscoe is positioned firmly in the aggressive hardtail category, best suited for trail riding.

The budget Roscoe 6 is the only exception, retaining a shorter-travel 120mm fork.

Frame features

With a more moderate level of suspension, the Marlin can double up for urban duties as well as hitting the dirt, so Trek has added a number of frame features with the commuter in mind.

You’ll find a mount for a kickstand as well as pannier rack mounts, so you can kit out your Marlin to carry luggage, whether that’s using it as a commuter bike around town or on a longer bike touring adventure.

The updated, third-generation Marlin frame also boasts internal cable routing for a dropper post, should you wish to add one later down the line. A rubberised chainstay guard comes pre-fitted to all Marlin models, to protect the frame from chain slap and minimise any noise.

As a more dedicated dirt shredder, the Roscoe doesn’t include the same rack and kickstand mounts, streamlining the frame.

Instead, you’ll find an in-built down tube guard in addition to the chainstay protector, designed to take the impact of stones and other trail debris.

You’ll also find ISCG mounts around the bottom bracket on the Roscoe, allowing you to fit a chain guide or bash guard.

Wheels and tyres

While most of the Marlin and Roscoe models on offer use modern 29er wheels , they do vary by frame size to offer the best fit for shorter riders.

For the Marlin, size XXS uses 26in wheels, sizes XS and S both use 27.5in wheels (also known as 650b ), while the larger sizes use 29er wheels.

There are slightly fewer sizes on offer with the Roscoe, starting with XS, which uses 27.5in wheels. With the exception of the Roscoe 6, which is built with 27.5in wheels across all sizes, the rest of the Roscoe models and sizes use 29in wheels.

While we’re talking rolling stock, one of the main differences between the Marlin and Roscoe is the tyre clearance, hence the width of tyres they are fitted with.

The new Marlin can accommodate up to 2.4in-wide mountain bike tyres with 29in wheels, whereas the Roscoe is fitted with plus-size 2.6in rubber, also with 29in wheels, for added traction. This wider rubber is fairly typical of trail hardtails, yielding extra grip in lieu of rear suspension .

To drop or not to drop

A dropper post is a key component when it comes to tackling trail features and steeper off-road terrain. You’ll find a dropper post included on some, but not all Trek hardtail mountain bikes.

A standard seatpost saves on both cost and weight, so with the exception of the top-tier Marlin 8, the Marlin family isn’t specced with a dropper. The good news is that internal cable routing means you can easily add one later though – a popular option when it comes to upgrading a mountain bike .

All Roscoe models are equipped with a dropper post from the get-go, correlating to their design for rowdier off-road pursuits.

With five models on offer, starting from a budget-friendly £475 / €599 for the Marlin 4 up to £1,230 / €1,349 for the Marlin 8, the Trek Marlin makes for an accessible entry to mountain biking. Third-generation Marlin models start from £760 / €849 with the Marlin 6.

The Roscoe starts at £1,160 / €1,299 / $1,199.99 for the Roscoe 6, though bikes from the Roscoe 7 (£1,620 / €1,799 / $1,899) onwards feature the latest frame, with the range topping out at £2,550 / €2,799 / $2,799.99 for the Roscoe 9.

You can expect to find an improvement in component choice and performance as you increase the amount you spend. For example, the base-level Marlin 4 is kitted out with Tektro M280 mechanical disc brakes, whereas the top-spec Marlin 8 uses more powerful Shimano MT200 hydraulic disc brakes.

It’s worth noting that Trek’s recent overhaul to the Marlin frame only applies to models 6, 7 and 8, whereas models 4 and 5 retain the previous frame design to help keep these entry-level options priced competitively.

Another good example of how the components differ between models is the wheel and tyre setup. The entry-level Roscoe 6 uses tubeless-ready rims but not tubeless-compatible tyres, the Roscoe 7 features both tubeless-compatible rims and tyres, though set up with tubes, and the top two Roscoe 8 and 9 models are set up tubeless from the get-go.

The quality and configuration of drivetrains change significantly as you move up through the models. All of the third-generation Marlin hardtails, and all Roscoe models, use modern 1x drivetrains , while the second-generation Marlin 4 and 5 use a triple chainring and double chainring respectively.

Trek Marlin vs Trek Roscoe, so which should you choose?

Despite initial appearances as fairly similar alloy hardtails, the Trek Marlin and Trek Roscoe are actually very different machines.

Choosing between them largely comes down to what sort of riding you’re planning, and whether you’d like to prioritise versatility or are seeking all-out trail capability.

Want something that’ll make for a great first mountain bike for teens and adults alike, with the added versatility to take you across town to work and back, as well as to the trailhead? The do-it-all Marlin is the smarter choice.

Looking for a ride that’ll level up to meet you as you progress over larger, steeper and techier trail features? Kitted out with a dropper post, progressive frame geometry, wide, grippy tyres and a beefy 140mm fork, the Roscoe is Trek’s dedicated trail option. There’s a reason it’s dubbed the ‘hardcore hardtail’.

Once you’ve worked out which sounds most like you, then you have a choice of four or five models, each with their own component options. Spending more as you work up through the models will give improved performance, as well as a lighter build, which will only help to widen your grin once you swing a leg over.

Can’t afford the top model from the outset? The good news is that both the Marlin and Roscoe have been designed to be upgrade-ready when the time comes.

Trek Roscoe vs Marlin: Which One Is Good?

Trek offers two great hardtail mountain bikes which are Trek Roscoe and Trek Marlin. Both bikes are designed for cross-country riding, with lightweight frames and suspension forks to smooth out the bumps.

Trek roscoe is a mountain bike that is designed for versatility. It can be used for commuting, weekend rides, or even intense downhill rides. The frame is made of durable aluminum, which makes it lightweight and easy to maneuver. It also has 27 speeds, which makes it suitable for a variety of terrain.

Marlin is a mountain bike that is designed for racing. It has a lightweight frame made of carbon fiber, which gives it a fast and responsive feel. It also has 29 speeds, making it suitable for a variety of terrain.

Trek Roscoe vs Marlin Key Differences

The main difference between Trek Roscoe and Trek Marlin is the frame material. Trek Roscoe uses aluminum frames while Trek Marlin uses Chromoly steel frames. This results in a difference in weight, with Trek Marlin being heavier. Both bikes are available in a variety of configurations, so you can find the perfect bike for your needs.

The Roscoe is a bit beefier than the Marlin, with 29.5″ wheels and wider tires. This gives it more stability and traction, making it ideal for rocky or rooty trails . It also has a longer wheelbase, which makes it more comfortable to ride at higher speeds. The downside of the Roscoe is that it’s a bit heavier and more sluggish on climbs.

The Marlin, on the other hand, has 27.5″ wheels and narrower tires. This makes it more nimble and faster on climbs, but less stable on rough terrain. It also has a shorter wheelbase, which can make it a bit twitchy at high speeds.

The Trek Roscoe is a great bike for those who want to get out and explore the trails. It has a suspension fork that helps to absorb bumps, and it also has wider tires that provide more stability on rough terrain.

The Marlin, on the other hand, is a great choice for those who want to race or go on longer rides. It has a lighter frame that makes it easier to pedal, and it also has narrower tires that help it go faster on smoother surfaces. There are a few key differences between the Trek Roscoe and Marlin bikes.

There is a significant weight difference between Trek Roscoe and Trek Marlin mountain bikes . The Roscoe tips the scales at 14.8 Kg, while the Marlin weighs in at 13.8 Kg. This weight difference can be attributed to the different materials used in the construction of each bike. The Marlin is made with lightweight aluminum, while the Roscoe employs heavier steel tubing.

This difference in weight can be a major factor for some riders, as it can affect how the bike handles and responds. Ultimately, it is up to the individual rider to decide which bike is best for them. Some riders may prefer the stability and durability of the Roscoe, while others may appreciate the lighter weight and better handling of the Marlin.

The Trek Marlin has a rigid Seatpost, while the Trek Roscoe has a dropper post. This means that the saddle can be lowered or raised on the Trek Roscoe without having to get off the bike, which can be convenient when traveling through steep or rough terrain .

Additionally, the Trek Roscoe has a bit more suspension travel than the Trek Marlin, making it better suited for off-road use. Ultimately, which bike you choose will come down to your own personal preferences and needs.

Groupset Difference

Trek Roscoe comes with an SX Eagle groupset, while the Trek Marlin comes with a Deore, FSA groupset. This means that the Trek Roscoe has a wider range of gears, which is better for climbing hills.

The Trek Marlin also has a lockout feature on the fork, which allows you to lock out the suspension when you don’t need it, which makes the bike more efficient when pedaling.

The Trek Roscoe is also available with an SX 1×12 drivetrain, which has an even wider range of gears and is better for climbing hills.

The Trek Marlin is available with a Deore FXA drivetrain, so if you want a mountain bike with a wide range of gears, the Trek Roscoe is the better choice.

Trek Roscoe and Trek Marlin are two mountain bikes with different wheel sizes . Trek Roscoe has a 27.5-inch wheel size while Trek Marlin has a 29-inch wheel size.

It also has 120mm of suspension travel, compared to 100mm on the Marlin, which makes it better suited for rougher terrain. The Roscoe is available in both men’s and women’s models, while the Marlin is only available in men’s models.

The two bikes are designed for different types of riding. Trek Roscoe is designed for cross-country and trail riding , while Trek Marlin is designed for mountain biking and all-terrain riding.

The Trek Roscoe has a lightweight frame and is designed for speed. It is perfect for cross-country and trail riding.

The Trek Marlin has a durable frame that can handle the demands of mountain biking and all-terrain riding. It is perfect for those who want a bike that can do it all.

Price Difference

There is a significant price difference between the Trek Roscoe and the Trek Marlin. The Trek Marlin is about $450 cheaper than the Trek Roscoe.

This may be due to the fact that the Trek Roscoe is a bit more basic than the Trek Marlin. The Trek Marlin has a few more features, such as a suspension fork, that may account for the price difference.

Trek Roscoe has an SX 1×12 drivetrain, while the Trek Marlin has a Deore 3×10 drivetrain. This means that the Trek Roscoe has a higher gear range than the Trek Marlin.

This can be important if you plan to do a lot of climbing on your bike. The Trek Marlin also has a derailleur guard, which can help protect the derailleur from damage in case of a crash.

Is Trek Roscoe Fat Bike?

Trek Roscoe is a fat bike that was designed to handle the toughest terrains. It’s perfect for riding on sand, snow, and other extreme surfaces. The bike has large 26×4-inch tires that provide stability and traction, allowing you to ride smoothly even when the surface is rough. Additionally, the frame is made from durable aluminum, so it can handle anything you throw at it.

Is the Trek Roscoe Good Trail Bike?

Yes, the Roscoe is a good trail bike. It offers a comfortable ride, efficient pedaling, and great handling. Plus, it’s capable of tackling a wide variety of terrain.

It’s durable, versatile, and efficient, making it perfect for off-road riding. Plus, its comfortable geometry and wide range of gearing make it suitable for a variety of trails.

Is Trek Marlin a Good Bike?

Getting to grips with 2018 Trek mountain bikes

If you pop over to Trek’s website and click on ‘mountain bikes’ more than 120 bikes appear in front of you. It’s rather daunting. Choice is good but can be bewildering. So we’ve boiled Trek’s MTB range down to the basics to get you started.

>>> Trek road bikes: which model is right for you?

What type of bike do you want?

We think it’s best to split the whole range into three categories and then go from there: hardtail , full suspension and electric .

What type of riding will you be doing?

Once you’ve chosen one of the three categories you can refine it to the type of riding you want to do: cross-country, trail or downhill.

With those two category types chosen you’ll be left with a much smaller pool of Trek models to consider.

We’re going to assume that you already know the type of mountain bike you want. We’re not going to go into any debates or theorising (hardtail vs full suspension, 27.5 vs 29 , Plus vs Fat etc etc).

Trek hardtails

There are five hardtail models in Trek’s range: Marlin, X-Caliber, Roscoe, Procaliber and Stache.

Trek use their own proprietary frame materials. Their aluminium stuff is called Alpha. Their carbon stuff is called OCLV.

Some of their high end hardtails have the ‘IsoSpeed Decoupler’ configuration where the seat tube is designed to flex for compliance.

The Trek Marlin is an entry level cross-country focussed hardtail ranging from £370 up to £550. Thee are four models in total (the Marlin 4, 5, 6 and 7). The frame is Trek’s ‘Silver Alpha’ aluminium.

The Trek X-Caliber cross-country range starts from £650 and tops out at £1,150. The frame is Trek’s ‘Gold Alpha’ aluminium. The frames have internal routing for stealth dropper seatposts. The components are of a higher quality than the Marlins.

The Trek Roscoe range of Plus-tyred trail hardtails running from £800 to £ 1,250. The frame has internal routing for dropper posts and is made from Trek’s ‘Alpha Gold’ aluminium.

The £1,300 to £6,500(!) Trek Procaliber cross-country race bike range can look a a bit confusing; there are aluminium Procalibers, OCLV carbon Procalibers and Super Light OCLV Procalibers. Although the frame material varies the intent of Procalibers is the same: xc racing. The geometry remains the same. All Procalibers have the ‘IsoSpeed Decoupler’ feature of deliberate flex.

The Trek Stache bikes are rather unique in that they are 29er Plus bikes. They roll on some seriously large rubber! Monster trucking hardtails. Price: £1,300 to £3,500.

Trek full suspension bikes

There are five Trek full susser types: Fuel EX, Remedy, Top Fuel, Slash and Session.

All Trek full sus bikes use a version of the ‘ABP’ suspension design. ABP stands for Active Braking Pivot. The rear wheel axle is also the rear pivot. The idea is to prevent the suspension from locking up during rear braking.

Fuel EX, Remedy and Top Fuel bikes also have RE:aktiv rear shock damping. This damping design claims to ‘know’ which forces are coming from the pedals/rider and which forces are coming from the trail, and it reacts accordingly.

The Trek Fuel EX 130mm travel, full sus, all-rounder, trail bikes come as either 29er or as 27.5 Plus. They can be run with either wheel size but are initially purchased with one or the other. Starting from £1,800 for aluminium versions they top out at £6,500 for the top end carbon version.

>>> Trek Fuel EX Plus 9.8 27.5 (2017) review

The Trek Remedy is the 150mm travel trail-cum-enduro bike. Prices range from £2,300 to £6,000. There are aluminium Remedy models and carbon fibre Remedy models. For 2018 they are all 27.5in wheel.

The Trek Top Fuel bikes are full suspension XC race machines. 100mm of travel at either end. Begins with the aluminium Top Fuel 8 for £2,400 and goes up to the £7,800 carbon Top Fuel 9.9 RSL.

>>> Trek Top Fuel 9 (2017) review

2018 Trek Slash

The 160mm travel enduro racing Trek Slash range is all 29in wheels and carbon only for 2018. It’s a bold move by Trek but one that makes the Slash arguably the most defined model in their range.

>>> Trek Slash 9.9 29 RSL (2017) review

The Trek Session is the downhill bike. Aluminium or carbon. And now available as a frameset as a 29er with 190mm of travel. Complete build Sessions are all 27.5in wheel and deliver 210mm of rear travel.

Trek electric mountain bikes

There are three electric mountain bike types: Powerfly, Powerfly FS and Powerfly LT Plus.

The Trek Powerfly hardtails start at £2,300 and go up to £3,300. Aluminium frames with 100mm travel forks up front. The motors come from Bosch. There is also a £4,200 Powerfly Plus with 2.8in tyres.

On the Trek Powerfly FS bikes the ‘FS’ stands for Full Suspension, 130mm of suspension to be precise. The Powerfly FS bikes are aimed at cross-country riding with a bit of rougher stuff every now and then. All but the entry level £3,500 Powerfly 5 FS come with Plus tyres.

Trek Powerfly Launch in Verbier, Switzerland

The Trek Powerfly LT Plus models have more travel (150mm) and fatter tyres (2.8in Plus tyres). These e-bikes are up for a bit more aggro riding and technical trails. Prices: £4,200 to £5,250.

Trek Women’s mountain bikes

Even as stalwarts of the whole Women’s Specific Design thang, Trek (along with most other bike brands) are now seemingly moving away from design theories that assume that women’s body proportions are different to men’s.

Bikes fit humans, not genders. Rider height is the only thing you should really be factoring in when choosing a bike. It really is only saddles that need to be a bit different to men’s.

It’s fine to opt for a supposedly ‘men’s’ Trek model if it fits your height. Get the saddle swapped out for a ladies saddle at time of purchase. Sorted.

Having said that, if you want a Women’s bike because you prefer the different colourway and decals, fair enough.

• Trek Skye – entry level cross-country hardtails
• Trek X-Caliber Women’s –  lighter and fancier cross-country hardtails
• Trek Roscoe Women’s – Plus tyred trail hardtail
• Trek Procaliber Women’s – XC racing hardtail
• Trek Fuel EX Women’s – 130mm travel full suspension all-rounder
• Trek Remedy Women’s – 150mm trail/enduro full susser
• Trek Powerfly Women’s – entry level e-bike hardtail
• Top Fuel Women’s – XC racing 100mm travel full suspension

Race Shop Limited models

You may spot some Trek mountain bikes with ‘Race Shop Limited’ (or ‘RSL’) in their model name. These are essentially super high spec models. Often limited edition. And sometimes with slightly tweaked designs (a bit more travel, slacker geometry etc etc).

X-Caliber and Procaliber Main Features

Let me now explain the most important features of the Trek X-Caliber bikes.

Frame and Geometry

All X-Caliber bikes have the same aluminum hardtail trail frame , available in many sizes and a few colors that vary between models. Procalibers have an OCLV carbon frame with an IsoSpeed decoupler (more about it later). They are also available in multiple colors and sizes.

Unlike Trek Marlin bikes , all sizes have the same shape and no curved top tube.

X-Calibers and Procalibers have almost the same geometry. It’s relatively average compared to other HT XC mountain bikes. Procalibers are slightly more aggressive. They have a slacker headtube angle, giving you more confidence when descending. Both will allow you to climb effectively.

So, the main difference between these two families is the frame material. Naturally, carbon frames are more expensive.

All X-Caliber and Procaliber mountain bikes have suspension travel of 100mm , suitable for cross-country. It can be limiting for riding demanding terrain or technical trails. For these terrains, consider Trek Roscoe instead.

Remember that the small sizes (XS) have a shorter travel (80mm) due to the small frame size.

The forks differ across all models, ranging from RockShox Judy SL (air spring) to RockShox Reba RL (Solo Air spring). These are not the best suspension forks on the market, but they are sufficient for these bikes’ intended use and price range.

Another difference between X-Calibers and Procalibers is the IsoSpeed decoupler found on Procalibers. You may know it from Trek road bikes . It absorbs small bumps and vibrations, making your ride more comfortable. It also reduces the strain on your lower back.

I have a friend who has experience with it. He told me it’s a cool feature, but it adds some weight and complexity to the bike.

Wheels and Tires

The wheel size is 29 inches on all Procaliber bikes. The smaller sizes of X-Calibers come with 27.5″ wheels, accelerating faster and more agile but offering less stability and speed than the 29-inch wheels.

The individual models also differ in the rims. The Procaliber 9.7 has carbon wheels (Bontrager Koove Elite 23). Other bikes come with aluminum rims only. However, it’s worth noting they are all tubeless-ready.

The X-Calibers come with wider tires (2.35″ vs. 2.20″). The higher-end Procalibers are equipped with better tires.

The X-Calibers and Procalibers differ mainly in their groupsets, which is often crucial for many buyers. The good news is that they come with 1×12-speed drivetrains.

1X drivetrains are popular because they are simple to maintain and shift and are lighter than 2X or 3X groupsets on some Trek Marlins .

However, the downside of 1X drivetrains is that they have a smaller gear range, which may make it challenging to find the right gear for your desired cadence.

Today, Shimano and SRAM groupsets have similar shifting speeds and precision. Therefore, you pay more for lower weight and slightly better performance.

The feature worth paying for more are the brakes. While all these bikes use hydraulic disc brakes, some use 2-piston, and some 4-piston ones.

The 4-piston ones provide better stopping power and are suitable for heavier riders or those who push their bikes to their limits.

The X-Caliber 8 and Procaliber 9.5 use 2-piston Shimano MT200 hydraulic disc brakes , while the other bikes use 4-piston brakes.

X-Caliber and Procaliber bikes have partially internally routed cables to improve their appearance. They have internal cable guides to prevent rattling inside the frame.

The X-Caliber 9 comes with a dropper post, while the other bikes don’t. However, they are compatible with them, so you can upgrade later.

Procalibers also have a Knock Block feature that prevents handlebars from spinning in a crash, preventing potential damage to the suspension, frame, etc.

All frames also have a double-sided chainstay guard . Procalibers also have a downtube guard for protection on rough terrain.

X-Caliber frames have mounts for kickstands and racks , making it easy to install these accessories. Procalibers don’t have them.

Lastly, all bikes except the Procaliber 9.7 come with lock-on grips that are easier to install and replace than slip-on grips.

Which mountain bike is better for you, the X-Caliber or the Procaliber, and which bike within each family offers the best value for the price?

In my opinion, the X-Caliber line is a good choice for those who want a hardtail MTB that is reasonably lightweight and fits a tighter budget.

The X-Caliber 9 appears to be a better value option due to its 4-piston hydraulic brakes, improved groupset, fork, dropper post, lower weight, and only being $330 more expensive.

On the other hand, Trek Procalibers are more appropriate for experienced mountain bikers who want a quality carbon frame.

The Procaliber 9.6 provides the best value, in my opinion, as it is less expensive than the Procaliber 9.7 but still offers a high-quality Shimano groupset and 4-piston disc brakes. Furthermore, you can always upgrade its components later.

Trek X-Caliber FAQ

Trek X-Caliber bikes are designed for recreational and entry-level mountain bikers who want a reasonably lightweight mountain bike. They feature durable aluminum frames, decent suspension forks, and reliable drivetrains. They are suitable for cross-country. However, their short travel may not be sufficient for too technical terrains, like rocky trails. Read this entire article for more info.

Trek Procaliber mountain bikes are perfect for riders looking to upgrade from an entry-level aluminum bike to a mid-range option. These bikes have a relatively aggressive geometry, making them ideal for cross-country racing. Their carbon frame keeps them lightweight, and the IsoSpeed decoupler provides a more comfortable ride. However, these bikes might not be suitable for challenging terrain due to their limited 100mm fork travel. For more information, read the full article.

X-Caliber and Procaliber bikes differ mainly in components like the groupset, fork, brakes, weight, and price. The difference between X-Calibers and Procalibers is the frame (aluminum vs. carbon) and other components. But they all have the same fork travel and use 1X drivetrains. I recommend reading this entire article for more information and a helpful comparison table.

Trek X Caliber 8 Review: Worth Buying Or Not?

• By Daniel Shakibaie
• Mountain Bike , Trek Bikes

Welcome to my Review for Trek X Caliber 8.

The Trek X Caliber 8 review for mountain bike s might be everything you’re looking for right now. It offers impressive rider handling and allows you to enjoy an adventurous ride in a variety of conditions.

Let’s take a look at this bike’s main features and benefits, along with some important factors to bear in mind when looking for your next mountain bike.

Things to Consider Before Buying a Smart Trail Bike

Before we look at the top factors of the Trek X Caliber 8, below are some important factors to consider when you buy a mountain bike.

Suspension System

There are two suspension systems to consider: hardtail and full. The former comes with a suspension system on the front of the bike, providing half of the shock absorption of a full-suspension bike.

Moreover, a hardtail bike offers a lighter weight overall, which allows you to ride the bike for longer periods of time without feeling like a heavy frame from weighing you down. Alternatively, a full-suspension bike is beneficial for absorbing all of the impacts and shocks that come your way, so you’ll typically feel more comfortable when riding across rough terrain and through woods, for example.

Body Case Material

Secondly, a bike’s body material makes a huge difference in its overall quality, speed, comfort, and more. The most popular body material option is aluminum, which offers a more affordable price compared to titanium, for example. However, aluminum can be more rigid than other materials for frames, meaning that it doesn’t absorb all of the impacts. One of the biggest benefits of a smart frame is its lightweight so that you can cycle quickly. And it’s also rust-resistant, so you won’t have any quality issues when you’re riding in the rain.

Alternatively, steel and alpha gold aluminum, an even more affordable bike body material, absorbs shocks when you’re cycling. This allows you to venture out on a variety of conditions without feeling the impact of every travel over rocks.

You might want to consider a titanium bike frame if you take cycling seriously and want to travel far and quickly. Thanks to this material’s lightweight, the bike picks up speed quickly and maintains this speed with ease. A titanium frame is incredibly agile, which allows the bike to respond to bumps in the road.

However, one of the biggest disadvantages of a titanium bike is its price point. You’ll need a larger budget compared to a steel or aluminum bike, which doesn’t make it appropriate for many riders.

Features and Benefits of the Trek X Caliber 8

Let’s take a look at some of the features and benefits of the Trek X Caliber 8 by taking an in-depth look into this bike’s top specifications.

The Trek X Caliber 8 comes equipped with a performance frame paired with allow rims, which has many benefits. For example, this material of the frame is naturally low in weight, making it an ideal choice for racing and travelling up hills, when you need to keep the overall maximum weight to a minimum.

Aluminum isn’t prone to rust, unlike steel bikes. So this makes the mountain bike low maintenance and ideal for regularly riding in wet conditions. Plus, due to aluminum’s lower strength compared to other bike materials, it tends to come with thicker walls. Therefore, you can use thicker-than-standard tubes without making the bike significantly heavier.

Moreover, the Trek X Caliber 8’s frame provides stiffness, which provides plenty of stability when climbing uphill or sprinting. And this level of stiffness will likely provide an advantage to racing cyclists because it offers an increased speed when sprinting.

This smart bike comes with a RockShox 30 Silver 100 mm suspension fork and a hardtail suspension system. These specifications allow the rider to feel the ride more than with a full-suspension bike, which allows you to experience an adventurist ride.

Another benefit of a hardtail bike over a full-suspension model is its reduced weight. Since the bike doesn’t have an additional shock system to the rear, the mountain bike has a lighter weight, which allows it to pick up speed and travel up hills quicker. And, with this weight saving, you can add accessories to your bikes, such as sports water bottles, fenders, and even a basket.

Uniquely, this trek bike features a smart wheel size, which means that you’ll receive either 27.5- or 29-inch wheels to accommodate a small or medium/large-sized frame. Therefore, the frame size will be perfectly paired with the bike’s tires, improving responsiveness, speed, and agility.

Moreover, the Trek X Caliber 8 ’s 27.5-inch wheels provide faster acceleration compared to the 29-inch wheels. This allows you to accelerate quickly and gives the bike a more responsive feel that riders will love.

Alternatively, the 29-inch wheels on this mountain bike accelerate slower, giving the bike a less responsive feel. But, once you reach your top speed, the bike maintains this for longer, requiring less effort to keep the momentum going. Not to mention that it’s actually a more efficient option for longer bike rides.

In addition, this smart trek bike comes with 12 speeds, which gives you more control when riding your bike. In particular, you can make the ride more challenging if you want to use it solely for fitness purposes. Or you can use the Trek X Caliber 8 to easily climb steep hills, making it a viable option for rides through the woods, etc.

The Trek X Caliber 8 is equipped with hydraulic disc brakes. Perhaps the biggest benefit of this type of brake system is that it automatically self-adjusts once they’re worn down. And the calliper’s design retracts a certain distance from the rotor, regardless of the pad’s wear level. Therefore, you don’t need to adjust the bike’s brakes as you would with mechanical pads.

Furthermore, these types of disc brakes dissipate heat evenly compared to traditional mechanical brakes. This means that the brakes are more likely to last a long time and can increase safety when you’re riding your bike.

Is the Trek Dual Sport 2 a Better Option Than the Trek X Caliber 8?

When comparing the Trek Dual Sport 2 to the Trek X Caliber 8, the trek dual sport 2 review: a worthwhile investment . With its versatile design and impressive features, the Dual Sport 2 offers a smooth ride on various terrains. On the other hand, the X Caliber 8 is a great choice for off-road enthusiasts looking for speed and performance. Ultimately, choosing between the two depends on your preferences and intended use.

Social Proof

Don’t just take our opinion on this bike ’s excellent performance. Below are some screenshots from customers and users of this bike and what they thought about how it rides.

Alternatives

Since you might want to keep your options open and put this mountain bike’s specifications into perspective, we’ve included a few comparisons with similar bikes.

Trek X Caliber 8 Review vs Trek Marlin 7

There are several differences between both smart bikes. For example, the Trek Marlin 7 features a kickstand, but the Trek X Caliber 8 bike doesn’t, which is an extra item that could catch on the trail.

A big difference between the bikes is the parts they’re made of. With the x Cal, you’ll get an air fork, whereas the Marlin bike comes with a coil spring. This difference in parts can affect how the bike feels on the trail. Check our guide to Trek Marlin 7

Trek X Caliber 8 vs Trek X Caliber 9

Both bikes come with 27.5-inch lightweight parts, but the Caliber 9 boasts a bigger fork and a slightly lighter weight (albeit it by 0.02 pounds). And the 9 Caliber comes with a 100 mm front travel, which allows this particular bike to absorb more shocks than the Caliber 8.

Trek X Caliber 8 vs Trek Roscoe 7

Both of these bikes feature a 27.5-inch frame of aluminum and are hardtail versions. However, the Roscoe 7 comes with a bigger fork and a dropper post. The Caliber 8 is the lightest of the two bikes by nearly three pounds, which might sound like a minute difference, but any additional weight on a bike can impact the overall power and momentum you have.

While the Caliber 8 has front travel of 80 mm, whereas the Roscoe 7 boasts a 100 mm front travel. Check our guide to Trek Roscoe 8

Trek X Caliber 8 vs Giant Fathom 2

Both bikes boast a performance frame, which helps to keep the bike’s weight at a minimum—ideal for when you’re cycling at high speeds. The Fathom 2 sports a 120 mm front travel, and while the Caliber 8 has a rigid seat post, the Fathom 2 boasts a dropper seat post, which allows for quick saddle height adjustment.

Trek X Caliber 8 vs Trek X Caliber 7

The Caliber 7 has a heavier weight, making the difference between the two bikes 0.8 pounds, which can be significant if you want to cycle fast and up hills. Aside from this specification and a difference of 20 mm for the front travel, both bikes are very similar. For example, they both boast an Alpha Gold aluminum frame, hydraulic discs, and hardtail suspension. Check our guide to Trek Caliber 7

We hope you enjoyed this Trek X Caliber 8 mountain bike review . Overall, this mountain bike was made with excellent attention to detail and the RockShox fork and hydraulic disc brakes make this bike a great option for adventure rides.

These types of mountain bikes have a loose ball bearing system with a solo air spring and a tapered head tube. This cross country mountain bike has the perfect frame size along with smart wheel sizing and sealed bearing. The wheels are made with lightweight alloy rims and have max chain ring size. These mountain bikes are a great choice for participating in the Maxxis Ardent race. It is a fast mountain bike with an alloy axle and a kickstand mount as well.

Some goofy geometry info listed, if indeed they're the same frame. No way that adding 2cm of travel to the fork will change the seat tube angle by more than 1 full degree - even on the smallest size frame.  

Effective STA would vary on both versions of this bike, contrary to what the website states.

I'm not a strong enough enthusiast to know a lot about bikes and handling etc.... so I like a bit of the feedback to how the subtle differences can make almost the same bike one format versus the other. I'm most impressed with the specs and comments on these as compared to my trail oriented bikepacker or adventure bike, steel, 1x11, Recon, Schwalbe and coming in a shade over 30# at $1199 new, a few months ago.  

I'm thinking about the rear hub "boost" 9*141 ??? Where in the aftermarket can you buy a new rear wheel if it gets broken. Why go back to QR when thru Axel has come to stay.... sad.  

Was really tempted by the Roscoe 8...solid build for the price. Ended up stretching the budget a tad more and got Diamondback Release 1...I'm so glad I went full squish.  

I'm somewhere between XC and novice trail. I like long days out in the British country side but also like to dick around on the trails. Does the Rosco also work well on the road as well as the trail? I like the idea of having the dropper post and bigger tyres but suspect this combine with the 1x11 would make it really difficult on a long day out. What are you thoughts?  

Gordon, I've got the Roscoe 9 (which is available in the UK) as my do-it-all bike. It handles roads fine albeit not at the pace that a 2-by bike could due to gearing, but where it shines is on climbs with some proper granny gears that help your legs keep churning. The plus size tyres (2.8" rather than 3.0" mentioned in the article) also eliminate any concerns over drain grid gaps (the enemy of skinnier hybrid/roadie tyres) and roll over most things with ease. Speaking of roll over, given the plus size tyres, some will say that they roll like 29ers rather than 27.5, but all I can say is that I have not had one single bad ride or found fault with the bike at all so far.  

The Trek website lists the X-Caliber's BB as being lower than the Roscoe's. So the statement about trail hardtails being lower than their XC counterparts isn't correct in this case.  

Just found this on the Q&A portion of the X-Caliber on the Trek website: Can you swap wheels between 29 and 27.5 plus like on the roscoe models? What is the maximum tire witdh. Verified Reply - Luke @ Trek No, this is not recommended. The tires will not fit in the frames that already use 27.5" tires. The 29er X-caliber has less fork travel than the Roscoe which will make the bottom bracket height too low for ideal riding performance if the X-caliber were to use 27.5+ wheels. 2.4" tires are the maximum recommended tire width for both the 27.5 and 29er X-caliber bikes. So apparently, the X-Caliber and Roscoe frames are not the same frame.  

yes you can swap wheel sizes the boost 141 is the same as 148 but with quick release trek has wheel sets ready to go

Me hice a la roscoe 8, y es destacada su respuesta en caminos difíciles y descensos pedregosos. La supensión es poderosa y la transmisión suave y fiable. La estética es impresionante, generando comentarios de los compañeros de ruta. El precio es mucho menor al de la competencia, y destaca en componentes frente a esta.  

Awesome review. I recently got a roscoe 7. I love it. For what it is meant for it is incredible. Great traction. Smooth ride. Fun bike. I love riding it in the snow. I am considering an x caliber 9 vs marlin 7 vs verv 3. I want it to be very fast, responsive and comfortable for mostly pavement and some light cc trail. It would replace my 2009 trek 6000 series mtb with 26x 2" wheels. It would also be used to pull a trek tag along. any suggestions? How does the xcaliber do on roots and rocks vs the marlin 7. I imagine the 29er xcaliber wheels will blow my 6000 series 26"wheels out of the water when it comes to overall speed? will the xcaliber be as nimble as my 6000 series or will it handle more like my roscoe 7? Will the xcaliber be as fast and responsive as a verv 3 on pavement?  

Estas seguro? Tengo una x caliber y el dato me sirve mucho para un futuro
