OVERVIEW
The Top Fuel 9.8 GX AXS Gen 4 is a lightweight carbon trail bike built to rip up climbs and stay playful on descents.

Plus, you can shift easy even under load with a SRAM GX Eagle AXS wireless transmission.
It's right for you if...
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 smooth-shifting performance of a direct mount transmission.
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 130 mm RockShox Pike Select+ fork with DebonAir spring, and Charger 3.1 RC2 damper, plus 120 mm of rear travel from a RockShox Deluxe Ultimate RCT shock. A SRAM GX Eagle wireless transmission, SRAM Level Bronze 4-piston hydraulic brakes, Bontrager Line dropper post and tubeless-ready Bontrager Line Comp 30 wheels.
The final word
If you're after a light carbon trail bike that balances a playful and capable ride, reach for the Top Fuel 9.8 GX AXS 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 a wireless SRAM GX AXS transmission and sweet RockShox suspension package.
