Trek Top Fuel 9.8 GX AXS 2024
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.
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, but don't mind saving some money on the parts.
The tech you get
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 new Shimano XT 1x12 drivetrain. Plus, wide carbon Bontrager Line Elite 30 wheels with a 108-tooth Rapid Drive hub for instant engagement, 4-piston brakes for confident descents, Bontrager Line Elite Dropper and carbon handlebars.
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 and more grip from the ultra-smooth suspension.
