2026 Trek Fuel MX 9 XT Di2 Gen 7 Aluminium Trail Mountain

The Fuel MX 9 XT Di2 is a playful trail bike made for hunting down side hits and chasing chaos. It features a robust Alpha NEXT Platinum aluminium frame paired with a top-tier Fox Factory suspension package (160mm front/150mm rear) and an MX (Mullet) wheel setup for a ride that is flickable and zippy. Shimano's wireless XT Di2 12-speed drivetrain delivers ultra-crisp, customizable shifting, while 4-piston XT M8200 brakes provide the modulation and stop-on-a-penny power needed when things get hairy.
