The Trek Fuel EX 8 XT 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.

In-frame storage and adjustable geometry give you all the perks that the come with the carbon model, but without the lofty price tag.
