This Fuel EX 8 GX AXS T-Type Gen 6 mountain bike is rated as an Excellent Grade, which reflects that the bike is in very good condition and can be considered to have been 'pre-pedalled'. Having been lightly used, there are some signs of use on the bike. The only minor visible marks are on the top tube, rear brake calliper, near drive side seat stay and head tube.

To ensure this bike meets our high standards for quality, it has undergone a thorough inspection by our professional mechanics. As with all our bikes, it comes with a 12-month Tredz warranty, plus any additional manufacturer warranty which may apply.

The lightweight alloy frame pairs with a upgraded electronic wireless 12-speed SRAM GX Eagle transmission, while a 150 mm FOX Rhythm fork cushions the blow from rocks and roots. In-frame storage and adjustable geometry give you all the perks that the come with the carbon model, but without the lofty price tag.

It's right for you if...

You want a full-suspension trail bike that floats over rough and technical terrain and packs in plusses, like a root-slaying FOX Rhythm fork and tubeless hoops.

The tech you get

SRAM's latest wireless GX Eagle AXS 12-speed transmission for snappy shifting and Tubeless-Ready Bontrager wheels. Plus, adjustable geometry that lets you take control of your set-up.
