The Trek X-Caliber 8 is a sure-footed 29er hardtail mountain bike, with plenty of reliable elements that boost its score to impressive levels, but a few missteps that hold it back from quite making it as one of the best hardtail mountain bikes we’ve tested. There’s a whole lot to like though.

Twenty nine inch wheels have long been an integral part of Trek’s mountain bikes, especially the hardtails. And where initially there was uncertainty and hesitation in the industry, Trek pushed on with this larger wheel size and the persistence paid off: with 29in wheels now accepted globally and across all mountain bike categories, not just for the cross country crowd.

Trek’s early 29in wheel bikes were XC hardtails and since then, the X-Caliber has shifted upmarket and now sit between the entry-level Marlin and the carbon Pro-Caliber. All three platforms run 100mm travel forks.

We’ve pulled in the X-Caliber 8 for this review, which is just shy of the Scott Scale 965 in price and shares many of the same components. With all four bikes on test running Shimano brakes and 1×12 transmissions, we were keen to take this consistency a step further and chose models with regular seatposts, rather than droppers. Primarily for comparing the weight of the bikes, but riding dynamics and overall value played a part too as we felt it really levelled the playing field, and maintained the XC hardtail design ethos.

With a steeply sloping top tube and a super-low standover height the X-Caliber is a very striking bike. It’s a silhouette that’s mirrored through all the brand’s hardtails – with the notable exception of the carbon Pro-Caliber – as is the wide size range that Trek is well known for offering. Seven frame sizes are available (with the XS and S rolling on 27.5in wheels to keep proportions in check) with a useful M/L option that’s a great problem solver for riders stuck between the popular M and L options. So hats off to Trek for this level of commitment to getting a good fitting bike.

When it comes to new frame standards, Trek has always been an early adopter, so it’s no surprise to see a tapered head tube and Boost hub spacing on the X-Caliber frame. But it’s Boost with a twist… here, Trek using 141mm rear dropout spacing with a traditional Q/R hub, rather than a 148mm bolt-thru design.

It’s not a deal breaker though, as the fixed rear triangle of a hardtail doesn’t need stiffening up like a full suspension design, and a quick online search reveals plenty of wheel upgrade options from the likes of Hunt, Hope and Bontrager for the 141 standard.

A modern touch that hasn’t been executed as well as on other bikes in test, is the internal frame routing for the cable and rear brake hose – they’re not clamped where they enter the down tube and rattle noisily on rough terrain, just like on the Trek Roscoe in our Hardtail of the Year test.

Trek has equipped the X-Caliber 8 with a RockShox fork and it’s listed as a Judy SL, so we expected to see an upgrade or two. However, all the tech is identical to the regular Judy forks seen on the Cube and Scott – a tapered aluminium steerer, steel upper legs, a Solo Air spring and the brand’s basic TurnKey damper.

The Trek is the only bike in test that doesn’t have a remote lockout lever though, just a simple dial on the top of the fork leg, with an on/off function and no graded adjustment between those points. At least it’s one less cable to maintain and gives more handlebar space for a dropper post remote lever.

And while the X-Caliber frame does not use a bolt-thru rear axle, the 100mm travel Judy fork does have the 15x110mm Boost hub standard – although the website lists the lighter tooled axle as standard, our test bike had the same QR lever operated version as the Scott Scale.

Shimano was slow to filter its 1×12 transmissions down to the lower price points, but it’s there now and proving to be a very popular choice, all four bikes in this test using Shimano drivetrains. The X-Caliber’s specification lists a Shimano chainset, but our bike shipped with a model from FSA, and it’s the only deviation from a complete Shimano drivetrain.

Trek has also gone with a smaller 30t chainring and combined with the Deore 10-51t cassette you get a super-low gear, which is useful on the climbs because at 13.53kg (29.82lb) the Trek is the heaviest bike in test.

Another wise move is the genuine Shimano chain which performs faultlessly in wet filthy conditions and plays well with the steel FSA chainring. The benchmark XT rear mech is good to see, as is the rubber chainstay protector, which is a detail the other three brands seemed to have overlooked.

Performance

The dropped top tube, wider 750mm bar, long wheelbase and slackish 68º head angle (the slackest of the four bikes) give the X-Caliber the look and feel of a trail bike. However, the Trek’s geometry and attitude is not in the same league as the most progressive 100mm trail hardtails such as Kona’s test-winning Mahuna .

Even on this size XL, the frame’s front triangle is very compact, especially when compared to the Giant XTC, but it still sports two sets of bottle cage mounts – essential on an XC bike. In fact, Trek has added plenty of mounts to the X-Caliber, with fittings for a rack and kickstand making it a very capable all-terrain bike.

With one of the lightest wheelsets on test, we expected some zip and liveliness from the X-Caliber but it lacked the immediate urgency of the Scott and Giant and on longer non-stop cross country blasts, its weight was noticeable, certainly towards the end of the ride.

You can’t knock the Trek’s sure-footed nature though – the lengthy wheelbase (for an XC hardtail) and wide bar aid stability, and it was only the Judy fork’s lack of refinement that held us back from diving into more challenging terrain. A slightly shorter stem would no doubt help here too.

Although the compact front end still has a tall 525mm seat tube, the seat stays are dropped, giving a tighter rear triangle. This certainly gives the X-Caliber a chuckable hardtail vibe, but the ride quality was a touch less compliant than the other bikes here.

With that in mind, there’s plenty of frame and fork clearance for higher volume tyres to help smooth the ride further, and Trek helpfully supplies the X-Caliber 8 with rim strips, valves and sealant so you can go tubeless straight from the box and reap the benefits immediately.

• Best hardtail mountain bikes
• Best mountain bike helmets: a bunch of brilliant brain-savers
• How to avoid arm pump when mountain biking

With a sure-footed ride, reliable Shimano components and a sorted tubeless wheelset, it feels like there’s a trail bike hiding under the X-Caliber’s glossy frame finish just waiting to get out, but being held back by the fork and lack of a dropper post. Stepping up a model to the X-Caliber 9 would be our recommendation then, as it gets a dropper post and a more capable and refined fork. Ultimately, the Trek X-Caliber 8’s weight is noticeable and even with the same control tyres fitted to all of the test bikes, the Trek lacks the race-bike urgency of the Scott and Giant.

Introduction

Are you going off-roading on rough trails or participating in cross country (XC) mountain biking?

There are many things you need to take care of when doing any of these activities. Before you get anything else done, however, you’ll have to start by choosing a reliable, high-quality bike.

Today, we’re going to check out what kind of companion the X-Caliber 8 from Trek Bikes is for your mountain biking trips.

Let’s get right into it and start with the complete guide on X-Caliber 8.

Our Guide to Trek X Caliber 8

Trek Biking Company has been making bikes since 1976. Across four decades, the company has built a reputation for crafting excellent, durable bikes that offer serious performance, regardless of your experience level.

The X-Caliber series from Trek Bikes takes this legacy forward with their XC mountain bikes. For the purposes of this review, we’ll be focusing on the X-Caliber 8 model only.

So, let’s get started with the features of Trek X-Caliber 8.

The X-Caliber series is a range of XC bikes all made of aluminum frames. These are lightweight bikes with a tapered head tube, and a rack and kickstand mount.

The internal cable routing helps to add to the neat appearance of these X-Caliber bikes.

X-Caliber 8 also features Boost 141 hub spacing that makes your frames stiffer and wheels stronger. It also gives you shorter chainstays, and more tire and chainring clearance. This allows you to ride on low-difficulty terrains with ease but isn’t suitable for particularly rough trails.

Like all XC mountain bikes, the X-Caliber also employs a lightweight geometry that gives you better pedaling efficiency.

The X-Caliber 8 is a hardtail bike, meaning that it does not have suspension in the back and the front suspension locks out. This makes biking on climbs and sprints easier.

The 1x SRAM drivetrain on this X-Caliber requires fewer gear adjustments which means a better biking experience for you with fewer chain drops. However, this configuration also offers fewer gear options.

If you’re looking for better flat-out speed, then a 2x or 3x drivetrain might be better for you.

The company has equipped the X-Caliber 8 with Shimano Deore front derailleur, Shimano Deore XT rear derailleur, and Shimano Deore 10-Speed shifters.

These speed shifters allow you to shift easily between riding positions with their 2-way release triggers.

The tire size will differ depending on the bike size you choose. Trek offers the following size options for its X-Caliber series:

• 29×2.4 inches for medium and large X-Caliber bikes
• 27.5×2.8 for small and extra small X-Caliber bikes

Versatility

Is the Trek X-Caliber 8 a versatile mountain bike?

The X-Caliber 8 is one of the most versatile bikes you’ll find on Trek’s list. The X-Caliber 8 allows you the freedom to go off-road or ride single-track marathons and races.

Can you take the X-Caliber 8 on long rides or touring? Absolutely!

The X-Caliber 8 is durable and will sustain you on long rides and touring as well. It is best suited for long trails with uphill and downhill riding.

Weight and Load Capacity

The medium-sized X-Caliber 8 weighs 28.77 pounds and its total load capacity is 300 pounds.

Braking System

Don’t forget about the braking systems!

This X-Caliber 8 mountain bike comes with the Shimano MT200 hydraulic disk brakes.

Hydraulic brakes are excellent for beginners because they do away with cables and also require less pressure. They are also lightweight so the bike’s overall weight is well adjusted.

But the Shimano MT200 brakes are the best for those looking to try MTB for the first time. These are quiet breaks that utilize one-way bleeding technology to prevent air from entering the hydraulic system.

What this means is your breaks and the hydraulic fluid in them will remain in optimum condition for years, without any need for regular bleeding and maintenance.

Want to add more flexibility to your seat’s height on those rocky terrains?

X-Caliber 8 is internal dropper compatible which allows you to upgrade your seat height limit whenever you want to.

At a rough price of $1,400, the X-Caliber is a cost-effective option among hardtail bikes which typically go up to $1,500.

Accessories

The bike features rack mounts that allow you to carry some accessories on those long trips you’ve been wanting to take.

Want to install accessories such as lights and computers on your bike?

Trek allows you to do that with its Blendr-compatible stem system.

Colors and Sizes Available

Trek makes its X-Caliber 8 in two different color options. One is a combination of lithium gray and trek black. While the other combines a radioactive red with trek black.

The X-Caliber 8 is available in a variety of size options from small and medium to large and double XL.

Trek X-Caliber 8 review

Trail confidence without breaking the bank

David Rome / Immediate Media

In 2014, Trek's X-Caliber (Skye for women) was re-born as a range of entry-level 29er hardtails. Just a year on, it's undergoing further changes, thanks to what Trek calls ‘Smart Wheel Sizes’ – that means smaller 650b hoops for the two smallest frame sizes, and 29in ones for every other size.

Given our near perfect experience with last year’s X-Caliber 7 , the sight of a RockShox branded fork on the new immediately had us smiling – although a corresponding price rise also has to be factored in. So is the new model worth the extra outlay?

Ride and handling: pro-level trail character with superb balance

The handling qualities of the last year’s X-Caliber 7 were a major factor in the praise we showered on it. Borrowing the geometry from Trek’s popular and World Cup-proven Superfly range, the 29in wheeled 7 rides like a performance bike, rather than the entry-level model that it is.

While smaller frame sizes will undoubtedly experience some difference in handling owing to their 650b wheels, our 17.5in-framed test bike immediately – and reassuringly – felt similar to the X-Caliber 7.

Out on the trail, the ride from the X-caliber's geometry shines

The spacious top tube, short stem combination means your weight sits evenly between the wheels, making for balanced handling. Factor in the relatively short rear end and you've got a comfortable riding position with easy manoeuvrability when the terrain requires. Meanwhile the wide, well-swept Bontrager handlebar offers plenty of leverage for confident control of the bike.

The front derailleur cable is routed internally through the top tube for a clean look

Plenty of handlebar height adjustment is available

It’s worth noting that the X-Caliber's responsive handling and undeviating climbing ability is only fully unlocked once the stem is lowered from its stock position. The bike's short head tube and a large stack of headset spacers allow for plenty of handlebar height adjustment options.

Rolling freely and with authority, the 29er wheels and large volume rubber take charge on rock and root infested trails. Smaller rocks and ripples in the ground go past unnoticed, with the RockShox XC32 fork doing a decent job at absorbing bigger hits – though sharp square-edged bumps can overwhelm it.

Along with a crown-mounted lockout and coil spring preload, the XC32 fork offers rebound control – something that is missing from cheaper models.

The RockShox XC32 fork works well in most conditions, though some flex becomes evident when it's really pushed

Unlike pricier steeds, the X-Caliber sticks with a standard 1 1/8in steerer and quick release axle. But it's only when you really push it that flex is felt in the fork – for most trail conditions, and most riders, it’s a non-issue. (It’s certainly stiffer than the 2015 X-Caliber 7’s XC30 fork)

Trek has also done a respectable job in smoothing the X-Caliber’s ride quality. While little compliance is offered by the alloy frame or firm handlebar grips, large 2.2in tyres go a long way towards filtering trail buzz. Combine this with a generously padded saddle that sits atop a skinny 27.2mm seat post, and the ride is by no means harsh.

It's worth bearing in mind though that while the X-Caliber is capable and eager to go just about anywhere, it does so more slowly than a fancier machine will. Whether you're hauling in speed for a fast approaching corner, conquering the steepest hill in the area or pumping the bike into the air, you're regularly reminded of the weight compromises – especially where it's carried by the wheels – that must inevitably be made with entry-level bikes.

Frame and equipment: well rounded build that’s capable of real riding

As mentioned above, depending on your size the 2015 X-Caliber frame goes through significant changes, or none at all. In the case of our 29in sample it’s the latter, with one exception in the form of brighter paint.

The frame is a fairly no-nonsense build featuring wide tyre clearance, internal front derailleur cable routing, easily serviced threaded bottom bracket and cleanly guided full-length sealed cable housing. Showcasing the potential versatility of the X-Caliber for commuting or light touring, the frame features both fender and pannier rack mounts out the back.

A bit of additional weld at the rear brake mount is used to reinforce the frame. Although it isn't the prettiest...

The build quality is pretty great, however, our brake hoses arrived a little long and messy. Good bike mechanics will clean this up before it reaches your hands, but if not, don't accept giant unnecessary loops in the hoses.

A 2x10 gearing system isn't commonly seen at the X-Caliber 8's price. But is it a good thing?

Given that this is the model above the previously tested X-Caliber 7, it’s no surprise the components are better. Beyond the front fork, the drivetrain is the next most obvious point of upgrade, with this model featuring a SRAM 2X10 system, more commonly seen on higher-end bikes. With 10-speed at the back and just two chainrings on the front, the X-Caliber’s gearing has been optimised for off-road use.

As discussed in our mountain bike groupset buyer’s guide , SRAM is Shimano’s key competitor and a popular choice in mountain biking. The X5/X7 components are an approximate equivalent to Shimano Deore and once set up correctly offer crisp and reliable shifting. It's still not as fast as more expensive options, but it didn’t miss a beat while being tested.

Gearing wise, the small chain ring and largest cog on the cassette enable you to crawl up even the steepest of climbs without too much stress. On the reverse, the 36T big chaninring is well suited to fast off-road use, though it may prove under-gunned for those looking to put a skinnier tyre on and commute. For such usage, other brands that stick with a triple chainring setup may suit you best.

Quality components where it matters

Something we don’t often sing about on bikes at this price is tubeless tyres. A tubeless setup allows for lower tyre pressures without the risk of flatting, so providing a smoother ride quality and greater traction on the trail. Additional benefits include lower weight and reduced rolling resistance. While the X-Caliber isn’t set up tubeless, it does feature tubeless ready rims that proved nicely off-road worthy.

In order to ditch the tubes, you’ll still need to buy the appropriate rim strips, tubeless-ready tyres and sealant, but it’s the single biggest upgrade you can do to the bike (after decent pedals) and it’s not a huge expense either.

Although the supplied Bontrager tyres are durable and confident treads for many trail conditions, they carry plenty of weight. Upgrading to tubeless with a compatible tyre would see the bike drop half a kilogram (and probably more) in weight.

We're big fans of Shimano brakes – even the cheapest models

While SRAM takes care of the drivetrain, Shimano handles the braking duties. This is a common and popular choice, because Shimano's entry-level brakes set the benchmark with reliable function and solid performance. The basic model on the X-Caliber lacks the precise feel and bite of more expensive models, but newer riders will quickly gain complete confidence in the system.

So we’ve covered what you’re gaining over the cheaper X-Caliber 7 , but it's also worth considering what you get at the next pricepoint up.

In some countries (including the US and UK), the X-Caliber 9 is also available and provides an example of what to expect. It offers an air-sprung fork for greater suspension tuneability and substantial weight savings. Additionally, the drivetrain components see a further upgrade that should aid in long-term durability. Finally, the hubs move to a sealed bearing unit – effectively creating a lighter system that use replaceable cartridge bearings instead of the cup and cone loose ball-bearing system found on the X-Caliber 8 and below.

Common advice when buying a starter mountain bike is to spend as much as your budget allows. As we’ve seen in our testing of the X-Caliber 8, that advice rings true in the form of lower weight along with suspension, gearing and wheels that are better suited to the punishment meted out by off-road use. Whatever your budget, be sure to factor in the cost of pedals, as those included won’t let you see what this bike is capable of.

Riding Experience

Regardless of the type of race, a fast descending is one of the best roads to outpace your opponents. And hardtail mountain bikes don’t get a lot of credit for comfortable descending.

When our testers rode the X-Caliber7, they were impressed with its light and nimble frame.

Even though it only has a RockShox Judy SL air fork with 100mm of travel, it’s more than enough for off-road terrain. In addition, the Trek X-Caliber 7 has 2.2-inch tubeless tires, which are fast and light, and can easily paddle over gravel on the way to fast descending.

What we marveled at in our many ride tests was its ability to descend quickly and nimbly. But all this performance can’t hide the fact that it has no dropper, has some vibration from rough ground, and is not as comfortable as its sibling, the Trek X-Caliber 9.

Combining its descending performance, we believe that it is not suitable for long-distance trail riding, but is more in line with the positioning of the Trek X-Caliber 7. The strong performance of off-road terrain is enough to let you participate in a race.

The Trek X-Caliber 7 is a fast climber in our opinion. This is also aided by its large 29-inch tires and 69.3° head tube angle.

Our testers have given the Trek X-Caliber 7 high marks with multiple rides on steep uphill roads and long uphill terrain, and while it’s not a brand new mountain bike, its performance still no less than the Trek X-Caliber 8 2022.

In the steep uphill road test, soft dirt was one of the obstacles to climbing. We needed to climb it fast to experience the comfort of the Trek X-Caliber 7. Of course, this also brings a problem, when we climb slower, it will be a little difficult. That doesn’t mean the Trek X-Caliber 7 doesn’t have room for improvement, and its front and rear tires can be expanded up to 27.5×2.80″ or 29×2.40″ wide tires. If you like to ride on winding uphill roads, you can do some replacements at the tires.

Since it’s equipped with a Shimano Deore 10-speed drivetrain, it feels a little underwhelming, and this is the biggest compromise this bike has made in components.

We like to ride it on long, gentle uphills, regardless of tire width. The 73° seat tube angle also keeps the body in a comfortable riding position, which can give full play to the rider’s riding skills.

General terrain

For a lightweight hardtail mountain bike, our main concern when riding in general terrain with little undulation is its ability to ride long distances.

The Trek X-Caliber 7 has designed the head tube angle, seat tube angle, and reach length to be as comfortable and fast as possible in the geometric design, so it still uses the same frame geometry in its follow-up models.

This bike converts well into a recreational mountain bike. It has a rear seat out for a rear rack, and two water bottle holders. In addition, he is also compatible with fenders, and has the characteristics of both adventure riding and leisure riding. It is hard not to like it.

It’s not easy to get tired on a long 20-mile ride. And the 10-speed drivetrain is exactly what you need.

If you want to travel by bike, it can support up to 20 pounds of weight in the back seat, so it is easy to take it to the campsite and go on an adventure with friends.

Main Features

Frame (4.9/5).

The X-Caliber features an Alpha Gold aluminum frame. Trek’s unique technology, the lightweight aluminum alloy is continuously cold-pressed to a fixed thickness, making it more durable.

This material allows engineers to better design and shape the tube according to your needs, and adjust the stiffness and adaptability of the tube accordingly. It’s designed this way to create a lighter, more responsive quality that’s ready to go with you anytime, anywhere. The frame reserves a large number of functional settings for competition use.

This bike is available in a variety of specs and price options. The trek x caliber 7 frame size is available in 7 different options and comes with the Dailed Fit system.

The high-quality RockShox fork is equipped with a locking function to ensure smooth, reliable, and adjustable suspension, able to absorb bumps caused by uneven road surfaces. The locking function on smooth surfaces allows the body to run at full speed while achieving greater riding efficiency.

In order to match the Boost 141 rear hub, the rear triangle of the frame has become wider, providing more tire clearance. At the same time, the length of the chainstays has been shortened, making the rear easier to handle when you are cornering.

The secret to the Terk, from my years of riding experience, is in its frame. Putting aside the drivetrain, this frame has a feel that sends power to the rear wheels almost every time you pedal. This feeling is very relaxing, and it gives the feeling that you want to leave others far away. It is not as slow as other mountain bikes, and the starting time will be longer.

When it comes to 29in, there is no other line with more history than the Trek and Gary Fisher lines. The X-Caliber inherits the sophisticated body geometry of the series, including Trek’s patented G2 design: a distinctive fork drift that makes the ride feel more dynamic.

G2 Geometry, advanced frame geometry, and a custom offset fork that allows precise handling of the 29ers at low speeds without compromising stability at high speeds, we call it G2 Geometry. Because our 29er handlebar is better than any other in its class.

The SR Suntour XCR fork has a diameter of 32mm, which helps to maintain stability in tight corners and rough roads. The rear shock is the base model, but it’s good enough, and the fixed rebound setting provides balance in the face of impact. I feel that the medium-sized bike tested is very suitable for riders of 70~85kg, and it can handle both large and small collisions with ease.

The front fork can be controlled remotely and can be locked in different positions to better cope with different terrains. The head tube uses a 1-1/8″ threadless, hidden bearing headset, taking into account the weight and strength, the large Trek Logo on the front of the car is very eye-catching, and the head tube has been reduced in diameter.

The short head tube and ample steering tube Length. The short head tube and long steerer tube provide plenty of handlebar height adjustment, and I was able to get to the right height easily with room to spare, which is not common on entry-level 29ers.

Components and Specifications

Drivetrain(4.5/5).

Given the entry-level price of the X-Caliber 7, compromises on components are inevitable. The X-Caliber 7 makes some compromises on the drivetrain, but it’s a wise decision.

Trek’s design philosophy has always been to configure high-end transmissions, and others can be ordinary, allowing customers to configure on the basis of Shimano.

For the 27-speed drivetrains on traditional older bikes, they have a lot of room to shift, and the Shimano Acera and Shimano Altus mix are ​​surprisingly good, but the rear derailleur isn’t stiff enough to hit the chain. The Acera has a good feel in the hand. This basic Shimano chainring is heavy and replaceable for convenience.

The transmission line tube adopts the inner wiring of the upper tube and the lower wiring of the whole tube, which can effectively avoid the problem of unsmooth shifting caused by muddy water pollution.

The cable fixing port is far away from the head tube, which can effectively give the shifting cable tube relaxation space and reduce the friction between the cable tube and the head tube. Built-in wiring provides a cleaner body appearance and easier transitions.

Wheels (4.7/5)

Tubeless-ready wheels are designed to reduce tire pressure for greater traction and control on bumpy, complex surfaces while reducing body weight.

The specifications of the wheels also reflect design excellence. We know that bigger wheels are faster, but smaller riders often have a hard time getting used to larger wheels. So we went with 27.5-inch wheels for smaller riders.

The medium and large frames are equipped with 29-inch wheels, which are more suitable for the fastest speed. This design approach is also known as smart wheel sizing.

The 29- and 27.5-inch wheels feature Trek off-road mountain-bike geometry, with short chainstays and a long top tube, which allow you to better distribute power and control the bike in the best way possible.

This is where the X-Caliber takes you to the winning finish on the mountain track.

Tires (4.7/5)

The Bontrager XR2 tires rolled smoothly and had good traction on dry ground, making them a perfect fit for this X-Caliber.

This tire has a good performance. The center tread on the tire surface is not only uniform and orderly, but also has a relatively compact connection in the center tread, so it provides good low rolling resistance and strong grip.

The front and rear wheels are different sizes, the front wheel is wider to increase traction, and the rear wheel is slender to reduce weight.

These configurations fully demonstrate Trek’s thorough understanding of off-road sports.

Brake (4.4/5)

Hydraulic disc brakes for better braking performance and control.

The Shimano M395 hydraulic brakes on the 2020 Trek X-Caliber 7 are high-performance, quiet, and affordable.

The only complaint is that the brake disc material is resin, so more durable hot-pressed brake pads cannot be used. Tektro adjustable brake levers are another highlight.

The rear brake caliper is installed inside the rear triangle of the frame, which can effectively improve the strength and make it more convenient to install the rack.

In the latest 2021 Trek X-Caliber 7, the brake system is upgraded to Shimano MT200 hydraulic disc, which improves the braking performance and makes it safer for mountain off-road.

Suspension (4.5/5)

Most models come with a 100mm front shock. It reduces the force of a collision, allowing you to maintain control at all times.

The smaller 13 5 size comes with an 80 mm suspension fork. Because of this, the center of gravity can be lowered even further while ensuring good control.

The X-Caliber’s fork has a locking lever that improves riding efficiency on smoother roads, long climbs, or standing sprints. The X-Caliber 7 design also has this suspension lockout feature.

A locked suspension means your fork remains inactive, increasing pedaling efficiency, and making it ideal for long stretches of road. In this condition, efficiency is more important than shock absorbers.

X-Caliber 7 Spece

• How do I determine what Bottom bracket I need?

An X-Caliber 7 bottom bracket that fits 73x113mm square taper is supported by the 2018 model.

• What is the width of the handlebars?

The Bontrager alloy is 31.8mm, has a 5mm rise, and measures 720mm wide.

• Hi, I was wondering if there were any differences between the 2017 and 2018 models? Thank you.

Almost all the parts on the bike are the same except the 2018 crankset is a double while the 2017 had a triple. The most significant change is in the frame! Unlike the 2017 frameset, the 2018 frameset is droppper post compatible.

• Is it possible to upgrade the 1×11 drivetrain on my 2018 X caliber 7?

Yes, the frame is compatible with 1×11 speed. Depending on the system you choose, you will need a new crank, bottom bracket, drivetrain, shifter, and perhaps a new rear wheel as well. For specific pricing and labor, please contact your local retailer.

• How much does a Trek Xcaliber 7 weigh?

Comparison Chart

Trek 820 vs trek x-caliber 7.

Both the X-Caliber 7 and the 820 are hardtail off-road bikes. The X-Caliber 7 has an aluminum frame, 27.5″/29″ wheels, better components, better, larger forks, and a 1×10 drivetrain that offers more gears; while the 820 has a steel frame and 26″ wheels. Explore the differences below.

Many customers complained to me about the weight of the 820. The steel frame of the 820 makes the overall weight reach 15.3kg, while the X-Caliber 7 uses an aluminum alloy frame and weighs only 13.4kg.

The X-Caliber 7 uses hydraulic disc brakes, while the 820 still uses rim brakes. Rim brake systems require heavy tracks for the pads to rest on. This requires the 820’s rim brake rim to be much heavier than the X-Caliber 7 disc brake rim.

The 820’s saddle is Bontrager Sport, which is so stiff that many customers change the saddle to a larger, more padded one after receiving it.

820 is the most affordable we introduce a series of mountain bikes, are those who are interested in mountain bikes, but still want to have a car as well as for hybrid bicycle light rail and city streets of beginner’s ideal choice.

Trek X-Caliber 8 vs Trek X-Caliber 7

Likewise, the X-Caliber 8 drivetrain is a 1 × 12 and the X-Caliber 7 drivetrain is a 1 × 10. So, the X-Caliber 8 is better for descents and sprints, while the X-Caliber 7 excels on climbs. And in terms of price, the two are closer. Of course, the X-Caliber 8 is a bit more expensive.

In terms of geometry, the two are exactly the same. The X-Caliber 8 is a replica of the X-Caliber 7.

In terms of kits, let’s talk about some of the models used by the two. Brakes, both use Shimano MT200 hydraulic discs. For the chain, the X-Caliber 7 uses a KMC X10, 10 speed, and the X-Caliber 8 uses a Shimano Deore M6100, 12 speed.

For the rear derailleur, X-Caliber 7 uses Shimano Deore M5120, long cage, and X-Caliber 8 uses Shimano XT M8100, long cage.

As can be seen from the above, the X-Caliber 8 is manufactured with special attention to value and the parts that have the greatest impact on performance.

Trek X-Caliber 9 vs Trek X-Caliber 7

The Trek X-Caliber 9 weighs 12.5 kg and the Trek X-Caliber 7 weighs 13.4 kg, not much difference.

The X-Caliber 9 drivetrain uses a 1 × 12 and the X-Caliber 7 drivetrain uses a 1 × 10. So the X-Caliber 9 is better for descents and sprints, while the X-Caliber 7 excels on climbs.

The geometry of the X-Caliber 9 and X-Caliber 7 is basically the same.

If we really want to compare, let’s take a look at the Top Tube Length. The X-Caliber 9 has 20 mm more top tube length than the X-Caliber 7.

This means you’ll be slightly stretched forward while riding the X-Caliber 9 than the X-Caliber 7.

Although the stack height and reach of the X-Caliber 9 are slightly longer than those of the X-Caliber 7, the stack height/reach ratio is still slightly larger than that of the X-Caliber 7, but there is only a gap of 0.03. I think it can be neglected.

In conclusion, the X-Caliber 9 is the high-end model in the X-Caliber family. It is a fully race-ready off-road mountain bike. The RockShox Recon fork, 1×12 Shimano XT/SLX drivetrain, and a wide-range cassette make it the best choice for fast singletrack riders.

Pivot Switchblade Race X01 vs Trek X-Caliber 7

The X-Caliber 7 is 27 mm lower than the Switchblade Race X01 stack. This means the X-Caliber 7 will keep you leaning forward during the ride, while maintaining a more comfortable upright position on long Switchblade Race X01 rides.

Therefore, we can see that the X-Caliber 7 is more inclined to be dedicated to competition, which can make you more aerodynamic.

The Switchblade Race X01 is better suited for some longer endurance road riding, its geometry puts your body weight further forward, helping you transfer power to the pedals more efficiently.

The length of the head tube (Head Tube Length) raises and lowers the rider’s position on the bike, the X-Caliber 7 is 90mm long, while the Switchblade Race X01 is 102mm, which is 12mm higher than the X-Caliber 7.

Geometric Gap

Under the assumption that the same wheel size and the same effect on the head tube angle result in the same head tube angle for the X-Caliber 7, the head angle is 3.5° higher.

The X-Caliber 7 head tube angle is steep enough to effectively climb technical singletrack at low speeds, yet slack enough to keep you from flying over the bars on descents.

The X-Caliber 7 is 21 mm lower in reach than the Switchblade Race X01. Compared to the Switchblade Race X01, the X-Caliber 7 will keep your weight farther away, helping to maintain rear-wheel traction on slick terrain or steep climbs.

Alpha Gold Aluminum is used in the construction of the X-Caliber 7, tapered head tube, internal derailleur & dropper post routing, rack & kickstand mounts, Boost141, and 5mm QR. The Switchblade Race X01 still uses the Switchblade, there is nothing special about it.

Final Evaluation (4.6/5)

The X-Caliber 7 is a full-featured 27.5-inch/29-inch hardtail cross-country mountain bike with mid-to-high-end components at a low-end price point for X-Caliber models, making it the perfect entry point for fast trail riding and racing.

The X-Caliber is the perfect choice for off-road racing, or it can take you on a variety of road conditions. Even if you’re not familiar with mountain biking, it can keep you hooked on the activity.

With its excellent frame design, lightweight alloys, and easily upgradeable body components, this affordable mountain bike with racing pedigree is the perfect entry-level mountain bike for many riders.

So we think the Trek X-Caliber 7 is a mountain bike worth buying. We ended up with a rating of 4.6.

As my Star Trek character commanded the weight of a starship, I was hours away from becoming a father

The lines between fiction and reality collided when i welcomed my child into the world.

Social Sharing

This First Person column is the experience of Patrick Kwok-Choon, who was born and raised in Montreal. For more information about CBC's First Person stories, please see the FAQ .

I was on the set of Star Trek: Discovery and my character Gen Rhys had been thrust into the captain's chair, burdened with making life-and-death decisions for himself and his crew.

I can't believe this was happening to me.

It was a milestone for my character — the first time as acting captain on the Starship Discovery — but also an important moment for me as a lifelong fan of the franchise.

Sitting in that chair, I couldn't help but think of the iconic performances by Patrick Stewart, Kate Mulgrew and Avery Brooks. The weight of their legacy was palpable, and being part of that tradition felt incredibly significant.

But my real concern wasn't the scene; it was the crisis unfolding at home.

At 3 a.m., my wife went into labour. When her contractions increased, we called our midwife at 9 a.m. Despite the unpredictability of childbirth, she assured me, based on her extensive experience, that it was OK for me to go to work. She mentioned that while it's not guaranteed, deliveries typically occur at night, offering me some peace of mind.

I was contractually obligated to go into work that day and my wife reassured me that her contractions were only uncomfortable, not painful. She insisted I go.

With a heavy heart, I asked my neighbour to watch over my wife and to call me if there was any emergency. I would come home immediately, regardless of the consequences.

When I arrived at work, my castmates greeted me with joy. The higher-ups were quickly informed and a production head came down to assure me that everything was being done to expedite my departure. The shooting schedule was rearranged so all my scenes would be filmed first. I immediately called my wife to share the news.

As I spoke with her, another production head approached, offering congratulations and reiterating the plan. But he added, "If things get too crazy at home and we haven't finished, just bail." I told him my wife felt we were still in the early phases of labour, and we should still have time. He leaned in, gave me a hug, and whispered in my ear, "Just bail."

All hands on deck

I was at a loss for words — studios aren't obligated to accommodate actors in such situations. I've heard terrible stories of actors unable to attend births, weddings and even funerals due to rigid shooting schedules. Yet here, amid the bustling set of a multimillion-dollar shoot, this person was giving me permission to prioritize my family. It was a heartfelt gesture that I'll never forget.

Returning to the chair, it felt like an actual "all hands on deck" moment straight out of Star Trek. Each department rallied together with precision and urgency, and I could feel their support willing me forward. Together, we navigated the challenges of the day, ensuring I could fulfill my duty as both actor and father-to-be.

After what felt like an eternity, the first assistant director called out, "That's a wrap on Patrick. He's free to leave."

I leaped out of my chair and shouted, "I'm going to have a baby!" to the applause of the cast and crew.

At this point, I had been at work for nine hours and it was 8 p.m. I rocketed out of that studio at warp speed. When I got home, my wife's contractions had reached the point where the midwife advised it was time to go to the hospital. I couldn't believe my luck. Despite the chaos of the day, I had made it just in time for the delivery.

Five hours later, as I held my newborn in my arms, I was overwhelmed with a sense of relief and profound joy. The juxtaposition of the day's events felt surreal — acting out life-and-death stakes on set only to experience the miracle of life in reality.

My child is now 20 months old. Just this weekend, I had the luxury of taking my child out for a morning stroll, pushing them for what felt like an eternity on the swings, and sitting in silence together on a park bench as I watched them slowly gobble up a muffin, basking in the absolute wonder of this little miracle. A gift. My gift.

I am miles away from the fearful day on set and have come safely to the other side of things – just as I'm light-years from my youth when I feared becoming a parent because, in my naive mind, it meant getting trapped into something or sacrificing my career, time and energy.

But I think most parents would agree: what you gain is absolutely priceless. No longer do I find myself consumed with work or clinging desperately to career aspirations. I have reshaped my understanding of what's really important to me and my life is immensely richer for it.

The day I spent in the captain's chair on Discovery will forever be etched in my memory, not just for the professional milestone it represented but for the personal journey it paralleled. The lines between fiction and reality blurred, the weight of commanding a starship colliding with the anticipation of welcoming new life into the world.

It was a stark reminder of the beautiful, unpredictable nature of life, where our most significant moments often unfold in the most unexpected ways.
