Trek 2021 X-Caliber 7


Embrace the thrill of cross-country riding with the 2021 X-Caliber 7 from TREK. This hardtail mountain bike boasts state-of-the-art technology in all the areas that matter — a lightweight yet sturdy alloy frame, a RockShox fork for smooth rides, a Shimano drivetrain for reliable shifts, and powerful hydraulic disc brakes for quick stops.

As a newcomer to mountain biking, you'll appreciate the X-Caliber 7's fine balance between value and performance. The bike has all the essentials you need for local XC trails and even for trying your hand at racing. And with its easily upgradeable features, the X-Caliber 7 is equally suited to keep pace with your skills as they advance on the trails.

At the heart of the bike is a lightweight Alpha Gold Aluminium frame equipped with a RockShox 30 Silver suspension fork. With this, you get 100mm travel and an air spring that's both lighter and more adjustable than a coil one. The Shimano 1x10 drivetrain delivers reliable gear shifts across a wide range, perfect for taking on uphill climbs. The X-Caliber 7 also comes with tubeless-ready wheels with wider Boost141 hubs, giving you stronger wheels with better tyre clearance.

What sets the X-Caliber 7 apart is the raft of high-end features it brings at its price point. From sleek internal cable routing and dropper post compatibility to a tapered head tube and Boost hub spacing, the bike is designed to keep up with your upgrades as you grow into the sport.

The RockShox air fork isn't just built to absorb bumps and shocks — it also comes with a rebound adjust and can be tuned to match the rider's weight. This level of customisation is far superior to what you'd find in most mountain bikes at this price range. Coupled with Smart Wheel Sizing that matches the wheel size to the frame for optimum speed and handling, the X-Caliber 7 is truly designed with your biking performance in mind.

Appreciate speed and efficiency with the X-Caliber's classic XC hardtail design. Its quick-handling geometry, coupled with weight-conscious components and just the right amount of suspension, makes it an ideal choice for those who aim to race or cover long distances in record time. The high-tech Alpha Gold Aluminum frame delivers precision handling up front and a nimble feel at the back, thanks to its tapered head tube and Boost 141 rear hub spacing.

With the X-Caliber 7, TREK makes high-quality cross-country riding accessible to newcomers and seasoned riders alike. It's more than just a mountain bike — it's your partner in growing your passion for the trails.
