Description

The Trek Fuel EX 9.8 XT Di2 is part of Trek’s 2026 mountain bike range. The Fuel EX 9.8 XT Di2 is a versatile and adaptable carbon MTB built to tackle any trail, at any time. Its OCLV Mountain Carbon frame pairs with a Fox Factory suspension package (145 mm rear, 150 mm front) to deliver traction and stability in the rough. Shimano’s iconic wireless XT Di2 12-speed drivetrain gives you robust, light and crisp customisable shifting, while 4-piston XT M8200 brakes provide excellent modulation and stop-on-a-penny power.
