Trek Top Fuel 9.9 X0 AXS T-Type Mountain Bike

TREK TOP FUEL 9.9 X0 AXS T-TYPE MOUNTAIN BIKE

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.

FEATURES

• Active Braking Pivot allows Trek 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.
• 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.
• Cleverly integrated into the steerer tube, the included BITS multi-tool has everything you need for trailside adjustments and repairs.
• 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.
• 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.
