Trek Fuel EX 9.8 XT Gen 6 Full Suspension Mountain Bike 2025 in Lava Red

Season:2025Sale

Brand:Trek

Code:41573RED

The Fuel EX 9.8 XT is a playful and capable trail bike that blends together cherry-picked components with a light full carbon frame for the best balance of price and performance. Decked out with 150 mm of front and 140 mm rear FOX Performance suspension package, you'll be ready to float through the chunder, while carbon wheels keep tracking precise through rowdy terrain. A Shimano XT drivetrain tops things off for precise shifting for power on descents and relief on long climbs.

It's right for you if...

You're chasing long flowy and technical descents, and want to pedal back to the top for more, lap after lap. You want the vibration-damping benefits of a carbon frame and carbon wheels, plus upgraded suspension that smooths out the rough and rowdy.

The tech you get

A light and stiff carbon frame with a full FOX Performance suspension package that smooths out rowdy rock gardens and root lattices. Plus, carbon wheels that keep your set-up light and tracking precise, and the clean shifting and brake modulation of a Shimano XT drivetrain. Finally, you'll find adjustable geometry and in-frame storage for keeping your set-up dialled just for you.

The final word

The Fuel EX 9.8 is the culmination of years of trail riding and progression, with longer front end geometry for tackling steeper and hairier descents, and a steeper seat tube to keep you perched on climbs. It's equipped with the cherry-picked components you want, like upgraded suspension, carbon wheels and a Shimano XT drivetrain.
