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.

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.
