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.
