Trek X-Caliber 7 Mountain Bike 2021
Serving as a great entry point to fast cross country racing and riding the Trek X-Caliber 7 Mountain Bike blends an infinitely upgradable frame with lightweight and dependable components.
The frame provides an efficient and responsive ride thanks to its lightweight but sturdy Alpha Gold aluminium composition. The Rockshox Judy SL fork partners this frame and increases handling accuracy across rough singletrack thanks to its plush air-sprung suspension. The geometry of the chassis is balanced but nimble allowing trails of all technicality to be conquered.
The robust aluminium wheels roll across the roughest of terrain with ease but are also light to facilitate quick acceleration and spritely changes of direction. The size of the wheel is adjusted to either 27.5” or 29” depending on the size of the frame. This Smart Wheel Sizing concept affords optimal control regardless of the rider's height. The rims are tubeless-tyre compatible, permitting an upgrade to this technology in the future.
The Shimano setup affords smooth gear changes while its 1x10-speed configuration allows any terrain, uphill or down, to be explored with ease. A hydraulic disc arrangement takes care of the braking duties, and grants modulated stopping power whatever the trail conditions.
