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. Our super-light OCLV Mountain Carbon frame, Bontrager Kovee Pro 30 carbon wheels with a 108-tooth Rapid Drive hub, SRAM XX1 Eagle 1x12 drivetrain, 100 mm 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.
