The bike that ruled the podium at the height of mountain bike racing is back to reclaim the top step. Refined and reinvigorated with new technology, Top Fuel is the fastest bike on the trail.
The better-than-ever Top Fuel is the fast, versatile choice for the cross country racer, marathon rider and the entire Trek Factory Racing World Cup team.
Advanced XC suspension
Proven Trek suspension tech like ABP, EVO Link and Full Floater are optimised for short-travel speed and efficiency, including a race-tuned shock.
Doubly stiff: Boost148/110
The wider 148mm rear and 110mm front hub spacing on 29ers creates stronger, less flexy wheels and allows for wider tyres, shorter chainstays and more chainring options.
G2: a better-handling 29er
Advanced frame geometry and a custom offset fork give you precise handling at low speed without compromising high-speed stability.
Smart Wheel Size
One wheel size does not fit all. We put the right size wheel on every frame: 27.5” on 15.5” frames, 29er on 17.5” and up. Everyone wins.
