Trek Fuel EX 9.7 Bike
Fuel EX 9.7 is our most affordable full suspension carbon trail bike. It pairs a lightweight, smooth-riding frame with a beefy 140mm FOX 36 fork, SRAM NX Eagle drivetrain, and powerful 4-piston brakes for a fast, fun mountain bike that’s a ripper now, and ripe for upgrades later.

Sizing & fit
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.
