Take the crisp handling, active suspension, and playful nature of the Fuel EX and bump it up to 29-inch wheels. You just became unstoppable. The Fuel EX 7 29 uses an Alpha aluminum frame and all the magic that puts Trek at the head of the pack. Things like the E2 head tube, and Full Floater and ABP rear suspension technologies make for a ride that obliterates the line between a hard-charging trail bike and nimble XC bike. The front and rear Fox suspension with CTD is responsive, plush, and handles hits way above its 120mm for that bottomless feeling without compromising a thing. Plus, Bontrager Race Lite components and Shimano gearing and discs feels like icing on the cake. Like we mentioned, unstoppable.
