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. Plus, you get the upgrade of wireless electronic shifting.
It's right for you if...
You’re looking for a do-it-all full-suspension mountain bike that is efficient yet can get rowdy. 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 SRAM GX Eagle AXS wireless 12-speed transmission. Plus, 4-piston brakes for confident descents, Bontrager Line Comp 30 wheels that are already set up tubeless, including sealant and a Bontrager Line Dropper.
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.
