The Trek 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.

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
