The Trek Top Fuel 9.8 GX AXS Gen 4 is a lightweight carbon trail bike built to rip up climbs and stay playful on descents. It gives you the confidence you want through roots and rocks, thanks to a 120 mm/130 mm RockShox suspension package with a Pike Select+ fork and Deluxe Ultimate shock. Plus, you can shift easy even under load with a SRAM GX Eagle AXS wireless transmission.

  • The Top Fuel Gen 4 delivers with an intensely lightweight build, improved in-frame storage and more adjustability for all kinds of rides and riders
  • With 120 mm rear and 130 mm front RockShox suspension, it delivers a well-balanced ride that stays efficient on the ups and playful on descents
  • The 4-way Mino Link makes it easy to adjust your geometry or leverage rate for how and where you want to ride
  • In-frame storage with an improved BITS bag system makes it easy to stash tools, tubes and snacks
  • It's more upgrade-ready than ever, with room for bigger 140 mm forks and longer-stroke shocks for up to 130 mm of rear travel, plus room for extra-long dropper posts
