Trek Fuel EX 9.8 XT Bike

Fuel EX 9.8 combines a light full-carbon frame with parts chosen for the highest performance-to-price ratio. High-end FOX suspension with upgraded front and rear dampers, carbon wheels with a Rapid Drive rear hub, and a super-smooth Shimano XT wide-range drivetrain give this model an extra edge you’ll notice from the first pedal stroke.

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
