Trek Top Fuel 8 NX 29" Mountain Bike 2020
The Trek Top Fuel 8 NX 29" Mountain Bike is a superb all-rounder, for tackling all kinds of terrain. The short-travel dual suspension system boasts an impressive 120mm via the RockShox fork, and Fox Performance Float rear suspension has 155mm of movement to absorb your landings. When it's time to sprint or power uphill, simply lock out both suspension systems with the flick of your wrist using the TwistLoc grip shift style lever.
The Bontrager Line Dropper seatpost allows you to quickly and easily put more weight over the rear wheel when the gradient pitches down. Adjust your geometry with the Mino Link, flipping the bottom bracket height up or down mid-ride should you need to favour stability or agility.
Specced with a SRAM NX Eagle 12-speed groupset, this is a premium machine that rolls on a set of Bontrager Kovee Comp tubeless ready clincher wheels.
- 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
