The TREK X-Caliber 8, shown here in blue, is a fast and responsive cross country mountain bike. Ideal to start a sport practice, it is made for speed. This semi-rigid ATV has a high-end aluminum frame that is very light. In this version 8, it is equipped with high-performance and robust components that are all-terrain-proof. There is a SRAM SX Eagle 1 x 12 speed transmission, a ROCKSHOX 30 silver suspension fork with 100mm of travel (80mm in Size XS) to provide the necessary damping and comfort on downhill and rough terrain, and finally SHIMANO MT200 hydraulic disc brakes to ensure efficient and powerful braking in all circumstances. Available in 2 wheel sizes depending on the frame size, the X-Caliber adapts to the morphology of the riders. This racy machine, ideally suited for cross-country mountain biking, is equally at home on rolling forest trails and technical single tracks.
