Detail
Overview
It's right for you if...
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 is critical, so you want a carbon frame and the cream of the crop parts, like an all-new, ultra-smooth Shimano XTR Di2 drivetrain.
The tech you get
An OCLV Mountain Carbon frame with a 4-way Mino Link lower shock mount for tweaking geometry and suspension leverage rate. A 130mm fork, plus 120mm of rear travel from a Fox Factory Float. Shimano's all-new XTR Di2 12-speed drivetrain, Shimano XTR M9220 hydraulic brakes, Bontrager Line dropper post, and tubeless-ready Bontrager Line Pro 30 OCLV Carbon wheels.
The final word
If you're after a light carbon trail bike that balances a playful and capable ride, reach for 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 Shimano's new XTR Di2 wireless drivetrain and a sweet suspension package.

Killer bike! Love how light and fast this thing is. Perfect for all-mountain riding. Shifting is spot on.

Just got my Top Fuel 9.9 XTR Di2 Gen 4 and took it out for a spin on the trails. Seriously impressed! The shifting is so smooth with the Di2, and the bike just eats up the climbs. Descending feels super confident too. Definitely worth the investment!

Just upgraded to the Top Fuel 9.9 XTR Di2 Gen 4 and wow, this bike is seriously amazing! Super responsive and climbs like a beast. The Di2 shifting is so smooth and precise. Definitely worth the investment if you're looking for a top-tier mountain bike. Been hitting the trails every weekend since I got it!

Seriously impressed with the Top Fuel 9.9. It's so smooth on the trails and handles everything I throw at it. The electronic shifting is a game-changer! The frame is lightweight but feels super durable. Definitely recommend!
