The Top Fuel 9.8 XT Gen 4 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 RockShox suspension package with a Pike Select fork and Deluxe Ultimate shock. Plus, you get clean shifts from a 12-speed Shimano XT drivetrain.
