It's right for you if...
You’re looking for a do-it-all full suspension mountain bike that balances efficiency with capability. You want to rip rough trails, do a couple XC races and even test yourself with an endurance or stage race.
The tech you get
A lightweight Alpha Platinum Aluminium frame, 120 mm RockShox Recon RL fork with Motion Control damper, 115 mm of rear travel with a Fox Performance Float shock and a 1x12 SRAM NX Eagle drivetrain. Plus, Shimano hydraulic disc brakes, TwistLoc dual remote suspension lockout, Bontrager Line Dropper and Tubeless Ready Bontrager Kovee Comp 23 wheels.
The final word
Top Fuel 8 is an efficient, capable and ridiculously fun short-travel full suspension trail bike. It's built to take on technical terrain, flowy XC courses and the demands of endurance mountain bike races.
Why you'll love it
