About this bike
From dunes to drifts, race to recreation, the Farley 9.9 lets you tackle anything, any time, for any reason. Fat Bike Nationals? Check. JP's Fat Pursuit? No biggie. All the singletrack you can fit into a Saturday on your own local trails? Definitely. Trek's legendary OCLV carbon frame features a 197mm-wide rear axle, which gives you short chain stays for snappy handling and the ability to run 26 x 5-inch or 27.5 x 4-inch fatties! The carbon Haru Pro fork offers the same clearance with a 150mm thru-axle and a tapered steerer that ensures dialed tracking. 85mm-wide HED Big Half Deal carbon rims sport Bontrager's Barbegazi 27.5 x 4.5-inch tires for a wide, extremely lightweight footprint and phenomenal traction. SRAM’s 12-speed XX1 Eagle drivetrain is your wide-range, go-anywhere transmission, climbing hills with ease and accelerating like a shot out of corners. And, scrub speed in a hurry with a mere squeeze of the SRAM Guide Ultimate brakes that offer precise all-condition control, so you can push your fun a little further. Your cockpit is chock-full of Bontrager’s XXX carbon components, which look as good as they perform and keep the weight down—because fat doesn't have to mean heavy.
