Trek X-Caliber 7 Mountain Bike 2020
It may be the entry-level model in the range, but you won't find yourself growing out of the Trek X-Caliber 7 Mountain Bike any time soon. The combination of an Alpha Gold Aluminium frame and RockShox 30 Silver fork ensures a strong and capable core to a build that's versatile enough for riding and racing cross country trails. 80/100mm of travel helps to smooth out bumps, but can be locked out for speed over more manageable terrain, while the rebound adjust is tuneable according to rider weight.
Wheels are frame size specific, with the two smallest sizes built up with 27.5", and the larger sizes with 29". The result is confident handling, excellent control and efficient rolling no matter which size you require. Boost141 hubs make the wheels incredibly strong and bring more clearance to fit wider tyres.
Ever-reliable Shimano components make up the groupset with a 2x9-speed drivetrain and hydraulic discs that take care of the braking. Internally routed cables reduce maintenance and are in keeping with the sleek aesthetics of the bike.
- It gets you into the world of cross-country riding and racing at a great price, and it's a mountain bike that can grow with you as your skills advance
- The sleek internal cable routing gives the bike clean looks, protects cables and makes it easy to upgrade to a dropper post for even more capability
- Smart Wheel Sizing means you'll get the fastest wheel that fits (29˝ wheels on larger frames, 27.5˝ wheels on smaller frames)
- The RockShox air fork has a rebound adjust and can be tuned to the rider’s weight
