Overview

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.

The Walkthrough

favorite_borderWhy 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

Features

High tech frame

The Alpha Gold Aluminum frame is packed with features that make your ride better. A tapered head tube gives you more precise, confident handling on the front end, while Boost 141 rear hub spacing gives you shorter chainstays for more nimble handling out back.

Built for speed

X-Caliber is a classic XC hardtail with quick-handling geometry, weight-conscious parts, and just enough suspension to take the edge off bumps. These models are built for efficiency, making them great for racers or anyone else who wants to cover more ground in less time.

Shimano XT

Shimano XT is the original mountain bike groupset and trusted by generations of mountain bikers around the world. Whatever the trail, wherever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high performance workhorse you can count on.

Smart Wheel Size

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

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.

Internal cable routing

We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.

Blendr-compatible stem

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