Trek Top Fuel 9.8 GX AXS

Top Fuel 9.8 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 parts package ? including a new SRAM GX Eagle AXS wireless electronic drivetrain ? with a low-weight carbon frame for one unbelievably fun rig that's fast on flow and fun to ride on techy singletrack.

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 blazing-fast wireless electronic shifting.

A light and stiff full carbon frame, 130 mm RockShox Pike Select+ fork, 120 mm of rear travel with a RockShox Deluxe Ultimate RCT shock and a SRAM GX Eagle AXS wireless electronic drivetrain with an extra-low 52-tooth climbing gear. Plus, wide carbon Bontrager Line Elite 30 wheels with a 108-tooth Rapid Drive hub for instant engagement, Bontrager Line Elite Dropper and carbon handlebars.

The Top Fuel 9.8 is a ridiculously fun carbon down-country bike with upgraded parts that give you big benefits on the trail, like more speed from the carbon wheels, more grip from the ultra-smooth suspension and faster, more precise shifts from the AXS drivetrain.
- The SRAM GX Eagle AXS drivetrain is smart, smooth and completely wireless
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- This bike?s killer suspension set-up is both efficient and ready to party
- Wider Line Elite 30 wheels provide better tyre support so you can run lower pressure and get more traction

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.

Quick and in control
120 mm 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 Storage
Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.

Hassle-free routing
Guided internal cable routing keeps Top Fuel quiet on the trail and maintenance a breeze.

Will my bike have a curved top tube?
The 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. The 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.

You almost forgot your pedals
This bike doesn?t come with pedals because you'll have a better ride if you choose your own. Explore the pedal guide to find the best pedals for your riding style. Reach for flat pedals for simple versatility or go for clipless MTB pedals if you want control and efficiency.
