Details

Top Fuel 9.8 SL is the full suspension XC mountain bike for riders who want every lightweight advantage. An OCLV Mountain Carbon frame, Bontrager carbon wheels, 100mm of suspension travel, and lightweight performance parts make this bike the perfect sidekick for serious XC riders who want a lightweight, durable rig for speed and efficiency on race day.

It's right for you if...

You don't want to ride trails, you want to fly across them—and you want a bike that can match you mile for mile through races and marathon singletrack sessions. You appreciate the performance advantage of carbon and want a superlight bike with race-level components and suspension.

The tech you get

An OCLV Mountain Carbon frame, a 1x12 SRAM GX Eagle drivetrain with an upgraded Truvativ Stylo carbon crank, wide carbon Bontrager Kovee Elite 30 wheels with a 54-tooth Rapid Drive hub for fast engagement. You get 100mm of front and rear suspension with a RockShox SID RL fork and FOX shock, plus a TwistLoc dual remote suspension lockout, and a carbon bar and seatpost.

The final word

Light, fast, and efficient. The carbon frame, carbon components, and efficient XC suspension make Top Fuel 9.8 SL right for riders who want a rocket of a bike to tackle cross country racing and marathons.

Why you'll love it

1 - This bike wants to go fast—it's built with no-nonsense, high-performance parts designed for flat-out speed
2 - TwistLoc simultaneously locks out front and rear shocks for climbs and sprints with the simple Grip Shift-like motion
3 - Wider Kovee Elite 30 wheels provide better tire support so you can run lower pressure and get more traction
