Trek Top Fuel 9.9 XX1 29" Mountain Bike 2020
The Trek Top Fuel 9.9 XX1 29" Mountain Bike is built on an OCLV carbon fibre frame, bringing lightweight performance for nimble handling and fast climbing ability. But that's just the beginning of this bike's head-turning credentials.
Impressively versatile, the Top Fuel might be the only mountain bike you ever need. The dual suspension system is tuned for a wide variety of trail terrain and really excels on endurance rides. When you need to put the power down, you can lock out both shocks at once at the flick of the TwistLoc grip lever. And when the trail changes from technical tight turns to fast-rolling sections, you can flip the geometry with the Mino Link and enjoy extra stability with a longer wheelbase. Get over the back wheel by dropping the seat post and descend with more comfort, safety and control.
The fast 29" Bontrager Kovee Pro 30 carbon wheels keep you rolling over small rocks and ruts and come tubeless ready. Gear changes with the SRAM XX1 Eagle AXS wireless shifters and derailleur are instant and satisfying, with no cables to fail or muddy up.
FEATURES
- The SRAM XX1 Eagle AXS drivetrain is smart, smooth and completely wireless
- It’s the ultimate endurance racing bike – light, capable and trimmed with high-performance components
- TwistLoc simultaneously locks out front and rear shocks for climbs and sprints with the simple Grip Shift-like motion
- This short-travel trail bike gives you a suspension set-up that’s capable in several MTB disciplines, and especially suited to endurance events
