Trek Top Fuel 9.7 NX Mountain Bike 2021

The Trek Top Fuel 9.7 NX 29" Mountain Bike is an adaptable machine that can take you down almost any trail while excelling in long-distance performance. The 120mm of travel on the front suspension softens ruts and rocks, while the rear shock absorbs 115mm of compression to help you land your jumps in comfort. Lock out both suspension systems by twisting the TwistLoc grip and attack the uphill sections. The intuitive Mino Link system adjusts bottom bracket height and can even be changed mid-ride so you can favour agility or stability. Drop the seatpost when riding aggressive downhill sections, and keep your weight over the back of the bike for more control. Rolling on a set of tubeless-ready Bontrager Kovee Comp 29" wheels, this is a fast bike, both uphill and down. The SRAM NX Eagle gears and Shimano hydraulic braking system deliver superb performance from two of the world's leading groupset manufacturers.


  • The full 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
  • TwistLoc simultaneously locks out front and rear shocks for climbs and sprints with the simple Grip Shift-like motion
  • Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride
  • You get a Straight Shot downtube for extra stiffness in the rough and Knock Block frame defence to protect against spinning bars and fork crowns
