The Trek Fuel EX 8 GX AXS is an evolved trail bike, dialled for riders who chase down rowdy descents and want a bike that's happy to pedal back to the top and do it again. 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.
