Top Fuel 9.9 is a full suspension carbon mountain bike for riders who don't settle. Not for parts nor for one style of riding. It combines a high-end component package with a low-weight carbon frame for one unbelievably fun rig that's fast on flow and fun to ride on techy singletrack.
It's right for you if...
You’re looking for a do-it-all full suspension mountain bike that's efficient and fast, but doesn't shy away from some bigger stuff. You want the added stiffness and weight savings of a carbon frame, and want parts packed with performance advantages.
The tech you get
A light and stiff OCLV Mountain Carbon frame, 130mm RockShox Pike Ultimate fork with DebonAir spring and Charger 3 RC2 damper, 120mm of rear travel with a RockShox Deluxe Ultimate RCT shock, and SRAM's wireless 12-speed X0 AXS direct-mount transmission that's as tough as it is precise. Plus, wide carbon Bontrager Line Elite 30 wheels with a 108-tooth Rapid Drive hub for instant engagement, 4-piston brakes for confident descents, a RockShox Reverb AXS Dropper, and carbon handlebar/stem combo.
The final word
Top Fuel 9.9 is a performance-built carbon down-country bike with top-tier parts that give you noticeable benefits on the trail, like more speed from the carbon wheels, more grip from the ultra-smooth suspension, and incredible shifting performance from SRAM's wireless X0 AXS transmission.
Why you'll love it
- You get the capability of a trail bike and the pedaling efficiency of an XC steed all wrapped up in one ready-to-party package
- Wider Bontrager Line Elite 30 wheels provide better tire support so you can run lower pressure and get more traction
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- SRAM's direct-mount T-Type wireless transmission delivers next level performance with precise shifts under load and unmatched durability
- Removable Knock Block 2.0 has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius
Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
Quick and in control
120mm of rear travel combined with progressive trail geometry gives you a fast, responsive ride that helps you keep your cool when the trail turns rowdy.
Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.
BITS: Your trailside savior
Cleverly integrated into the steerer tube, the included BITS multi-tool has everything you need for trailside adjustments and repairs.
Transition to transmission
SRAM Eagle T-Type transmission mounts directly to the frame, skipping that pesky derailleur hanger of yesteryear. This makes for a more robust system that's not only cleaner looking, it's also more precise under load, and easier to set up.
Guided internal cable routing keeps Top Fuel quiet on the trail and maintenance a breeze.
Will my bike have a curved top tube?
Smaller frames (XS and S) have a curved top tube. This design makes for a lower standover height, which allows shorter riders to straddle the bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don't have the same issues with standover height.
