  1. Loading...

Top Fuel is a fast and light full suspension XC mountain bike. This quick-handling ride is designed for speed and efficiency on singletrack and cross country trails, and it’s equipped with Trek-exclusive MTB tech that keeps you comfortable and in control when the trail gets rough. It’s a great choice for racers, long-distance riders, and anyone who wants more traction and capability than a hardtail can offer without the weight of a full-on trail bike.

More control, more speed

Trek's patented Active Braking Pivot keeps your suspension working even when you're on the brakes. It gives you more traction and control and makes for a more efficient ride so you can stay stronger longer.

Advanced XC race spec

Every Top Fuel is equipped with parts chosen for speed and efficiency, like a SRAM Eagle 1x12 drivetrain, lightweight RockShox suspension fork, and TwistLoc dual suspension remote lockout. Plus, select models roll on wide carbon rims.

Smart Wheel Size

One wheel size does not fit all. We put the right wheel size on every frame, so everyone gets the fastest wheel that fits: 27.5˝ wheels on 15.5˝ frames, 29er wheels on 17.5˝ and up.
