Trek Top Fuel AL Frameset Mountain Bike
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.
Quick and in control
120mm of rear travel combined with progressive trail geometry gives you a fast, responsive ride that helps you keep your cool when the trail turns rowdy.
Knock Block
Knock Block has your frame’s back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won’t get yanked, and your controls won’t hit the top tube.
Internal Storage
Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.
Hassle-free routing
Guided internal cable routing keeps Top Fuel quiet on the trail and maintenance a breeze.
Will my bike have a curved top tube?
Smaller frames (XS and S) have a curved top tube. This design makes for a lower standover height, which allows shorter riders to straddle the bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
