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.

BITS: Your trailside savior

Cleverly integrated into the steerer tube, the included BITS multi-tool has everything you need for trailside adjustments and repairs.

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.
