Trek Top Fuel 8 Mountain Bike

About the Top Fuel 8

The Top Fuel 8 fuses the speed of a cross-country bike with the capability and forgiveness of a full-suspension trail bike. It's quick and nimble, and dishes out serious fun on flow trails and techy descents alike

Key Features

• Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently


• 120 mm 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


• Internal frame storage makes it easy to ditch the pack and still carry your ride essentials


• Guided internal cable routing keeps Top Fuel quiet on the trail and maintenance a breeze


• New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius


• Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride
