Trek Supercaliber 9.9 XTR Mountain Bike 2021
Low in weight and high on performance, Trek’s Supercaliber 9.9 XTR Mountain Bike has been designed to excel on modern XC race courses and fast cross-country rides. The carbon frame houses an IsoStrut FOX Factory shock giving 60mm of travel for better traction and control, whilst also reducing the number of pivots needed for less weight and increased stiffness. At the front end, the RockShox SID SL Ultimate fork provides 100mm of travel to keep the bumps in check, and both front and rear suspension units can be locked out at the same time with one motion using the TwistLoc remote on the handlebar when required.
Shimano’s range-topping 12-speed XTR groupset never disappoints, with snappy, reliable shifting and beautifully engineered designs. The combination of the 10-51t cassette and 34t chainring gives a wide choice of ratios whether racing or just enjoying a rapid local route, and the XTR hydraulic disc brakes are more than able to keep things in control no matter the conditions.
Bontrager’s Kovee XXX 30 carbon wheels are wide enough to ensure that the XR2 Team Issue tyres are well supported in the corners and as both are tubeless-ready the conversion is simple. The premium finishing kit is also supplied by Bontrager, with the carbon handlebar, carbon seatpost and carbon railed saddle maintaining the high-end theme of the bike.
