The Trek Fuel EX 9.9 makes no compromises. Top-shelf suspension, carbon everything and SRAM's latest X01 Eagle drive train make this ripper ready to rule any trail in style. It's fast, it's light, and it's got everything you need to crush your next trail ride.

Fuel EX 9.9 is for riders who want the best in everything. It's dripping with carbon and has the latest in suspension and drive train tech
RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
The Fox Factory 36 fork gives you four-way damping adjustments, plus you get Kashima Coat for smoother, more durable stanchions
We expanded our size range to ensure a better fit for all riders. And, you get the fastest wheel that fits your frame: XS frames get 27.5˝ wheels, S frames get to choose between 27.5˝ or 29˝ and sizes M to XL get 29˝ wheels
Make it yours: it's fully customisable through Project One
