Trek Fuel EX 8 Review

The Fuel EX 8 GX ranks high among adventurous trail bikes for mountain bikers. Its full suspension system enables riders to compete favorably in short and long-distance bike races. It has a rigid Alpha Aluminum frame that supports top performance while delivering stability and reliability. Fully engineered with Fox performance Float EVOL rear shock riders are assured bump-less maneuvers even in the worst of mountain trails.

Upgraded Suspension System

The Trek Fuel EX 8 GX has a firmer suspension system. Compared to previous models that had a plusher suite, the Thru-Shaft damper helps to increase the end of travel and make for better riding. The shock and fork are adjustable to help support weights and adapt to various road types. The fork is made with a Fox 36 Rhythm material with four spacers in a 68-psi EVOL air spring.

Fortified with SRAM Eagle Drivetrain

The Trek Fuel EX 8 GX trail bike has a multiple speed drivetrain for changing the gear smoothly for different speeds. Also adding to the lot is the Deore hydraulic disc brakes from the stables of Shimano that ensure the bike’s speed is kept in check at whatever speed the rider is going.

With an incredible Fox float EVOL rear shock the mountainside would feel like level asphalt as all bumps would be adequately soaked up by the efficient shock absorbers.

Stronger Bontrager Carbon Tires

This is one of the most essential features of the Trek Fuel EX 8 GX. The tires are fitted with Carbon 30s Bontrager Line materials. These are arguably one of the best products in the market. They have tubeless wheels, with TLR Bontrager sealants to prevent any air leakage during riding. The rider only needs to open the valve cores and add some drops of adhesives and voila! The bike is good to go. The wheels have 29-mm carbon rims lined with TLR strips.
