Trek 2026 Top Fuel 9.8 XT Di2 Gen 4
The Top Fuel 9.8 is a lightweight carbon trail bike built to rip up climbs and stay playful on descents. It gives you the confidence you want through roots and rocks, thanks to a 120 mm/130 mm (rear/front) RockShox suspension package with a Pike Select+ fork and Deluxe Ultimate shock. Plus, you get ultra-smooth and fast shifts from a 12-speed Shimano XT Di2 wireless drivetrain.
