X-Caliber 9

Overview

You measure your rides in speed and distance, and want a fast XC bike that will help you cover more trail in less time. You race, or you could see yourself getting into racing, so you want a hardtail with competition-level parts that can give you an advantage on the trail.

A lightweight aluminium frame, a RockShox Recon Gold RL100 mm suspension air fork and a Shimano XT/SLX 1x12 drivetrain with a wide range of gears for easier climbing. Plus, tubeless-ready wheels with wider Boost141 hubs for increased wheel strength and better tyre clearance, and a dropper post for getting low on descents.

The X-Caliber 9 is a speedy, nimble and efficient XC hardtail that's perfect for riders with a racing pedigree and anyone who dreams of covering epic distances out on the trail.

It's a great bike for someone who's just getting into serious racing: you get high-end XC parts on an incredible frame with enough cash left over for entry fees
There's nothing as sweet as a silent ride: the clutch rear derailleur prevents chain slap, even in the rough
The frame is fully compatible with higher-end parts, like racing wheels, if you ever find the need to upgrade
The 1x drivetrain delivers a wide range of gearing with the simplicity of a single shifter

X-Caliber Frame Set

Features

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.

The Alpha Gold Aluminuum 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 at the back.

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

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

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

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