Trek Supercaliber 9.8 XT Mountain Bike 2021
The key to its performance lies in the 60mm of travel from the unique IsoStrut design, which offers good traction and control but with less of a weight and stiffness penalty than longer travel bikes. With 100mm of travel from the FOX Performance 32 Step-Cast fork, the front end is equally well glued to the ground, soaking up bumps and ensuring that there is grip aplenty in the corners.
Carbon is very much the material of choice elsewhere on the bike, with the handlebar, seatpost and rims all made from it, keeping the weight down and performance at race-worthy levels. The Bontrager Kovee Pro 30 wheels and XR2 Team Issue tyres are both tubeless-ready, and the extra width of the wheels works well to give additional support to the sidewalls in fast corners.
Shimano’s XT M8100 12-speed groupset provides nearly all of the performance of the range-topping XTR components with a far more wallet-friendly price. The 10-51t cassette has ratios for steep hills and fast descents, whilst the shifting is typically Shimano, being fast and precise at all times. XT level hydraulic disc brakes help keep control of proceedings with tireless performance and easy modulation in all weather conditions.
