Trek Top Fuel 8 Trail Bike 2020 Review

The Top Fuel 8 is a trail bike that makes for competitive mountain and endurance biking events. It is equipped with features that make it adequately suited to cope with the rigors of trail biking. The Alpha platinum aluminum frame, hydraulic disc brakes, suspension fork system, and tubeless tires make it a hardcore endurance bike. The TwistLoc feature also makes for easy ascents and descents.


Straight shot geometry

The versatility of this mountain bike is courtesy of the Straight shot geometry design. This enables trail riding on any terrain with great bike handling, steady body balance. The bike responds to sudden movements of the rider because of the even distribution of the rider weight. The geometry of the bike can be adjusted by making use of the Mino Link flip. Adjustments do not affect the performance of the fork suspension.

Tubeless tires

Top Fuel 8 is furnished with tubeless-ready tires. This is feature ensures that the tires are well adapted to take on different mountain trail terrain. They provide great surface traction, puncture-resistant, and light. As a result, the biker is able to handle the bike well, maintain body balance and consistent momentum. The efficient hydraulic disc brakes also complement the tires, by providing sufficient stopping power when required.

Efficient braking technology

This mountain bike comes with an efficient braking system. This is courtesy of the ingenious braking technology by Trek, known as Active Braking Pivot (ABP). This brake suspension technology enables steady and very responsive braking capacity when required, without skidding. It also soaks up all-terrain impacts and promotes additional riding resilience. This enables the biker to have smooth control on any topography and in closed junctions without fear.
