Trek X-Caliber 8 Mountain Bike 2020
Capable and affordable, The Trek X-Caliber 8 Mountain Bike is based around a lightweight Alpha Gold Aluminium frame with internal cable routing for clean lines and smooth running. The RockShox 30 Silver fork is air-sprung and has an adjustable rebound that can be tuned to the rider’s weight, with 100mm (size XS - 80mm) of travel for better comfort and control on rough surfaces. It also has a lockout function for greater efficiency on smoother surfaces.
Shimano’s MT200 hydraulic disc brakes provide powerful all-weather control whilst the SRAM SX drivetrain uses a single front ring paired with a large cassette for simplicity of operation and a wide range of ratios. The larger frame sizes use fast-rolling 29” wheels and tyres for better cross-country efficiency whilst the XS and S sizes have 27.5” wheels in order to keep the handling and ride feel more consistent across the range.
