Trek Fuel EX 9.8 XT (Gen 7) Full Suspension Bike 2026

Fuel EX 9.8 XT is a versatile and adaptable carbon MTB built to tackle any trail, anytime. Its OCLV Mountain Carbon frame pairs with a Fox Factory suspension package (145mm rear, 150mm front) to deliver traction and stability in the rough. A mechanical Shimano XT 12-speed drivetrain gives you clean, reliable shifting and 4-piston XT M8200 brakes provide excellent modulation and stop-on-a-dime power.
