New Arrivals/Restock

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 120mm/130mm (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.

• Upgraded components, like the iconic Shimano XT Di2 wireless drivetrain and a RockShox suspension package make this Top Fuel ride like a dream
• Top Fuel Gen 4 delivers with an intensely lightweight build, improved in-frame storage, and more adjustability for all kinds of rides and riders
• With 120mm rear and 130mm front RockShox suspension, it delivers a well-balanced ride that stays efficient on the ups and playful on descents
• The 4-way Mino Link makes it easy to adjust your geometry or leverage rate for how and where you want to ride
• Its more upgrade-ready than ever, with room for bigger 140mm forks and longer-stroke shocks for up to 130mm of rear travel, plus room for extra-long dropper posts

Make Top Fuel yours

Opt for light parts and a 120mm fork for a featherweight Top Fuel, or a 140mm fork and longer-stroke 130mm rear shock for extra versatility. Room for a longer dropper and MX wheels lets you customize Top Fuel into an ultimate playful trail whip.

4-way Mino Link

Easily adjust the suspension and geometry four different ways for where and how you ride. With the flip of a chip, you can ride with more or less progressive suspension, and tweak your geometry for a slacker head tube and lower BB or steeper head tube and higher BB.

New internal storage with new BITS bags

New internal frame storage bags make it easy to ditch the pack and still carry your ride essentials.

Active Braking Pivot

Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
