Trek Top Fuel 9.8 GX Mountain Bike 2021

Crafted from stiff, light OCLV Carbon and premium performance parts, the Trek Top Fuel 9.8 GX Mountain Bike is rapid and raises a smile on endurance rides or more technical trails. The slack head tube makes for a more planted feel and heightened confidence at speed, while the Mino Link means the geometry can be adjusted, even mid-ride; drop the bottom bracket and slacken the head angle by half a degree, or keep it responsive in a more aggressive position. Front and rear RockShox suspension are ultra-smooth, soaking up rough terrain and keeping fatigue at bay. For explosive sprints and challenging climbs, the front and rear shocks can be locked out remotely, and the Bontrager Line Elite Dropper seatpost gets the saddle out of the way in an instant for descents or sweeping corners.

The carbon Bontrager Kovee Elite 30 wheels save on weight and can be run tubeless to avoid punctures at low pressures, whilst also providing improved traction and grip. Mid-level SRAM GX Eagle 12-speed components are consistent, lightweight and durable - shifting reliably and with an array of gearing options to suit undulating gradients.


  • The full OCLV carbon frame gives you a light, responsive ride
  • This short-travel trail bike gives you a suspension set-up that’s capable in several MTB disciplines, and especially suited to endurance events.
  • 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 efficiency
  • Wider Kovee Pro 30 wheels provide better tyre support so you can run lower pressure and get more traction
  • Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride
  • 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
