Trek Top Fuel 8 Full Suspension Mountain Bike 2024
Trek Top Fuel 8 Full Suspension Mountain Bike 2024
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.
It's right for you if...
You’re looking for a do-it-all full-suspension mountain bike that balances efficiency with shred-ability. You want to rip rough descents, fly up climbs and crush lap after lap.
The tech you get
A lightweight aluminium frame with internal storage, 130 mm RockShox Pike fork with plush DebonAir spring, 120 mm of rear travel with a RockShox Deluxe Ultimate RCT shock and a Shimano XT drivetrain. Plus, 4-piston brakes for confident descents, Bontrager Line Comp 30 wheels that are already completely tubeless-ready, including sealant and a Bontrager Line Dropper.
Why you'll love it
- This bike’s killer suspension set-up is both efficient and ready to party
- You get wide Bontrager Line Comp 30 wheels that boost grip and reduce flats with their tubeless setup
- Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius
The final word
The Top Fuel 8 gets you the value of an alloy frame with drivetrain, fork and brake upgrades that keep up as you progress in speed and skill.
