Trek Fuel EX 9.8 GX AXS T-Type Gen 6 (2025)

Ideal for you!

You want a full suspension bike capable of following you everywhere. You’re looking for the vibration-dampening benefits offered by a completely carbon frame-wheel combination and a high-quality suspension package capable of devouring the rockiest trails. You appreciate the clean and minimalist setup of a 12-speed wireless drivetrain.

The technology you get

A lightweight and stiff carbon frame paired with a FOX Performance suspension package that turns rock gardens into a smooth ride. Carbon wheels that reduce weight while providing a rigid and reliable solution. Additionally, the SRAM GX AXS 12-speed wireless drivetrain and tubeless tires allow you to spend less time fixing flats. Finally, the integrated frame storage and adjustable geometry ensure you always have the perfect setup at hand.

The final word

Fuel EX 9.8 is the evolution of years of trail riding, with a longer front geometry to tackle the most challenging descents and a more vertical seat tube to get back to the top for another lap. The carbon frame ensures maximum lightness while the SRAM GX AXS drivetrain offers an elevated ride for those who appreciate the latest technologies.
