The Top Fuel 9.9 XTR Gen 4 is a lightweight carbon trail bike built to rip up climbs and stay playful on descents. It gives you the confidence you want through roots and rocks thanks to a 120 mm/130 mm RockShox suspension package with a Pike Ultimate fork and Deluxe Ultimate shock. Plus, you get clean shifts from a premium 12-speed Shimano XTR drivetrain.

You're after a carbon trail bike that keeps weight to a minimum without compromising on capability. You like to ride everything - long alpine climbs, rooty aspen slalom, fast XC singletrack and you want a bike that can keep up on the ups and hold its own on the downs. Keeping things light with a carbon frame is important to you, and you want the light yet precise shifting of a Shimano XTR drivetrain.

An OCLV Mountain Carbon frame with a 4-way Mino Link lower shock mount for tweaking geometry and suspension leverage rate. A 130 mm RockShox Pike Ultimate fork with DebonAir spring, and Charger 3.1 RC2 damper, plus 120 mm of rear travel from a RockShox Deluxe Ultimate RCT shock. A Shimano XTR 12-speed drivetrain, Shimano XTR M9100 hydraulic brakes, Bontrager Line dropper post and tubeless-ready Bontrager Line Pro 30 wheels.

If you're after a light carbon trail bike that balances a playful and capable ride, reach for the Top Fuel 9.8 XTR Gen 4. Its ultra-lightweight frame pairs with a 4-way Mino Link lower suspension mount for taking control of your geometry and suspension feel. Plus, you get clean shifts from a Shimano XTR drivetrain and a sweet RockShox suspension package.
- The Top Fuel Gen 4 delivers with an intensely lightweight build, improved in-frame storage and more adjustability for all kinds of rides and riders
- With 120 mm rear and 130 mm front RockShox suspension, it delivers a well-balanced ride that stays efficient on the ups and playful on descents
- The 4-way Mino Link makes it easy to adjust your geometry or leverage rate for how and where you want to ride
- In-frame storage with an improved BITS bag system makes it easy to stash tools, tubes and snacks
- It's more upgrade-ready than ever, with room for bigger 140 mm forks and longer-stroke shocks for up to 130 mm of rear travel, plus room for extra-long dropper posts

Make the Top Fuel yours
Opt for light parts and a 120 mm fork for a featherweight Top Fuel, or a 140 mm fork and longer-stroke 130 mm rear shock for extra versatility. Room for a longer dropper and MX wheels lets you customise the Top Fuel into an ultimate playful trail whip.

4-way Mino Link
Easily adjust the suspension and geometry four different ways for where and how you ride. At the flip of a coin, you can ride with more or less progressive suspension and tweak your geometry for a slacker head tube and lower BB, or steeper head tube and higher BB.

New internal storage with new BITS bags
New internal frame storage bags make it easy to ditch the pack and still carry your ride essentials.

BITS: Your trail-side saviour
Cleverly integrated into the steerer tube, the included BITS multi-tool has everything you need for trail-side adjustments and repairs.



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.



Shimano XTR
Designed to meet the highest level of competitive mountain bike racing needs, with second-to-none performance and experience, Shimano XTR M9100 brings lightweight, high-end versatility to XC, enduro and marathon racing.
