Trek Top Fuel 8 NX Mountain Bike 2021
Featuring a lightweight and durable Alpha Platinum Aluminium chassis and plush front and rear suspension, the Trek Top Fuel 8 NX Mountain Bike is the kind of go-anywhere bike that eats up trails and even excels in XC races. It's efficient, nimble and versatile thanks to features such as the Mino Link, which allows geometry to be adjusted mid-ride - lower the bottom bracket and slacken the head tube angle by half a degree for trail-oriented riding or keep it in the high setting for a more aggressive position.
Lock out the front and rear shocks simultaneously for powerful sprints and testing climbs, and for descents, the Bontrager Line Dropper seatpost gets the saddle out of the equation quickly. For added confidence when speed ramps up, the responsive SRAM Level T hydraulic disc brakes come in useful. SRAM NX Eagle 12-speed components lend rugged reliability to this build, ensuring snappy shifting and gearing options galore.
Highlights
- The Alpha Platinum Aluminium frame is lightweight, capable and forgiving
- 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
- 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
