Trek Fuel EX 9.8 GX AXS T-Type Gen 6 Full Suspension Mountain Bike 2025

The Fuel EX 9.8 GX AXS is a trail-charging machine that packs a punch on the singletrack with a lightweight and stiff carbon fibre frame that damps jarring vibrations and holds its own when you pick a line. It's loaded with the tech you want, like SRAM GX AXS wireless shifting for remarkably reliable shifting under load, plus a 150 mm front and 140 mm rear FOX Performance suspension package that smooths the roughest trails. It's all topped off with carbon Bontrager wheels that shed weight and keep tracking precise.

It's right for you if...

You want a full suspension ride that can handle anything you throw its way. You want the vibration-damping benefits of a carbon frame and wheels and rock-gobbling premium suspension, and appreciate when you can keep your set-up clean and minimalist with wireless 12-speed shifting.

The tech you get

A light-and-stiff carbon frame with a full FOX Performance suspension package that turns chunky rock gardens into smooth sailing. Carbon wheels that keep weight down while offering stiff and reliable tracking. Plus, the wireless shifting of SRAM's 12-speed GX AXS transmission, and tubeless hoops and tyres so you can spend less time fixing flats. Finally, you'll find adjustable geometry and in-frame storage for keeping your set-up dialled just for you.

Why you'll love it

• The Fuel EX Gen 6 gives you 140/150 mm of travel with extra adjustability features and more stable handling, plus a more robust frame with internal storage
• It comes equipped with light and stiff carbon wheels that make quick work of technical terrain and keep you on your line when things get hairy
• You get the latest technology in SRAM's GX AXS 12-speed transmission for precision shifting – even under load, plus a FOX Performance suspension package
• With the adjustable angle headset (angled cups sold separately) and Mino Link, you can choose from six different geometry configurations
• We expanded our size range to ensure a better fit for all riders, and use the best-fitting wheels for each frame size: XS frames get 27.5˝ wheels, S frames get to choose between 27.5˝ or 29˝, and sizes M and up get 29˝ wheels

The final word

The Fuel EX 9.8 is the evolution of years of trail riding, with longer front geometry for taking on steep descents, and a steeper seat tube for hammering back up to do it again. Its carbon frame keeps things light, and SRAM GX AXS shifting takes things up a notch for those who want the latest tech.
