It's right for you if...

You're looking for a fast mountain bike for singletrack—one that's fully capable of taking on races, marathons, and competitive group rides. You want something that is reliable and fun with dependable, lightweight parts.

The tech you get

A lightweight aluminum frame, a RockShox Judy SL 100mm suspension fork with a TurnKey lockout and an air spring that's lighter and more adjustable than a coil spring, tubeless ready wheels with Boost141 hub spacing, and a Shimano Deore 1x12 drivetrain with a wide-range cassette.

The final word

With X-Caliber 8, you're getting a performance frame paired with performance parts, like a RockShox air fork and 1x Shimano Deore drivetrain. Plus, it's equipped with durable, lightweight alloy rims that save weight and are easy to upgrade to tubeless.

Why you'll love it

1 – It has the price of a more basic hardtail, but the parts and performance of a more expensive one

2 – The frame is fully compatible with higher-end parts, like race wheels and a dropper post, if you ever find the need to upgrade

3 – Smart Wheel Sizing means you’ll get the fastest wheel that fits (29˝ wheels on larger frames, 27.5˝ wheels on smaller frames)

4 – The 1x drivetrain delivers a wide range of gearing with the simplicity of a single shifter

Alpha Gold Aluminum

Our high-performance lightweight aluminum is continuously cold extruded and butted, and formed into manipulated tube shapes to balance strength and weight saving.

Smart Wheel Size

The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.

Blendr-compatible stem

Bontrager Blendr stem technology lets you clip your gear directly to the stem for clean looks, maximum user friendliness.

Dropper post internal routing

Not ready for an internally routed dropper post now, but want to keep your options open? Select frames are equipped with the proper entry and exit points to accommodate internal routing for a Stealth seat post.

Suspension lockout

Locked suspension means your fork remains inactive, increasing pedaling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.
