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 and wireless electronic drivetrain with a low-weight carbon frame for one unbelievably fun rig that's fast on flow and still fun to ride on techy singletrack.

It's right for you if...
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 the performance upgrade of a fully wireless electronic drivetrain.

The tech you get
A light and stiff full carbon frame, 120mm RockShox SID Select+ fork, 115mm of rear travel with a RockShox SID Luxe Ultimate shock, and a SRAM GX Eagle AXS wireless electronic drivetrain with an extra-low 52-tooth climbing gear. Plus, wide carbon Bontrager Kovee Elite 30 wheels with a 54-tooth Rapid Drive hub for fast engagement, Bontrager Line Elite Dropper, and powerful 4-piston brakes.

The final word
Top Fuel 9.8 is a ridiculously fun carbon down-country bike with upgraded parts that give you noticeable benefits on the trail, like more speed from the carbon wheels, more grip from the ultra-smooth suspension, and more precise shifts with a SRAM AXS drivetrain.

Why you'll love it
- The SRAM GX Eagle AXS drivetrain is smart, smooth, and completely wireless
- You get a Straight Shot downtube for extra-stiff, responsive handling without added weight, and a Knock Block headset that protects against spinning bars and fork crowns
- Bontrager DropLock's shifter-style lever lets you easily lock out both front and rear shocks at the same time for added sprinting or climbing efficiently. Plus, it controls your dropper post too
- Wider Kovee Elite 30 wheels provide better tire support so you can run lower pressure and get more traction
- This short-travel bike has a killer suspension setup reminiscent of the all-mighty mullet—it's both efficient and ready to party
