Top Fuel 9.9 SL is Trek's fastest full suspension XC mountain bike. Everything on this bike is geared toward helping you go faster and perform better. An OCLV Mountain Carbon frame, carbon components, and super-lightweight full suspension setup make Top Fuel 9.9 SL a race-ready rocket that flies over gnarly terrain on its way to the podium.
It's right for you if...
At night, when you're lying in bed after a hard ride, you close your eyes and dream of carbon and the best XC parts available. Whether you're racing or training, you want to be the fastest. You want a bike that exceeds expectations in all categories—light weight, strength, speed, and efficiency.
The tech you get
Here's the truth: there's not much on this bike that isn't carbon. Trek's superlight OCLV Mountain Carbon frame, Bontrager Kovee Pro 30 carbon wheels with a 108-tooth Rapid Drive hub, SRAM XX1 Eagle 1x12 drivetrain, 100mm front and rear suspension with a super-light and super-plush RockShox SID SE fork. Plus, a TwistLoc dual remote suspension lockout, SRAM Level Ultimate carbon brakes, and a carbon handlebar and seatpost.
The final word
So. Much. Carbon. This is hands down the fastest full suspension XC mountain bike we make, trimmed with the best parts out there. A full OCLV Mountain Carbon frame, top-of-the-line suspension, and carbon components come together in Top Fuel 9.9 SL to make the fastest bike on the line. The rest is up to you.
