Trek Fuel EX 9.9 X01 AXS Mountain Bike 2021
Combining the ultimate performance and convenience of SRAM’s fully wireless 12-speed shifting with top-notch FOX shock units and Trek’s OCLV carbon frame makes the Fuel EX 9.9 X01 AXS Mountain Bike an extremely worthy trail-ready machine. The font and rear suspension offer 140mm and 130mm of travel respectively for great control and traction, with the Kashima Coat adding an extra layer of plushness to the already impressive performance. Nestled within the rear shock’s linkages is the Mino chip, which can be flipped over to slacken the head angle and drop the bottom bracket for greater high-speed stability, whilst the Knock Block design protects the down tube from being hit by the fork crown in the event of a crash.
SRAM G2 RSC hydraulic disc brakes ensure rapid, fade-free stopping power on even the steepest, fastest trails with the AXS wireless shifting immune from cable stretch and dirt contamination for consistently perfect shifting every time. The RockShox Reverb dropper seat post is also controlled by the wireless AXS system, while the AXS smartphone app allows functions to be customised and performance monitored.
Carbon is the favoured material elsewhere too, with the rims and the handlebar benefiting from its high strength and low weight. Bontrager’s XR4 Team Issue tyres are tubeless-ready as are the Line Pro 30 wheels, making the conversion a simpler task.
