The Fatback Corvus is an all-terrain carbon fat tire bike that's made for the elements. The Corvus utilizes the strength of a unidirectional carbon fiber layup, with a monocoque front triangle and bonded chainstays and seatstays. With its integrated rack mounts and maximized storage capacity in the front triangle, riders can carry a wide range of gear while taking advantage of the lighter and stiffer frame that carbon fiber offers.

The Corvus has a tapered headtube, 100mm standard threaded BB, 3 bottle mounts, 197mm rear spacing utilizing a 12mm thru-axle - which means you can fit some fat ass tires in there. 31.6 seat-tube (so droppers work fine). The tapered steerer carbon fork has room for a 4.8 tire, has a 42mm offset, 160mm post mount brake, 15mm thru-axle, and is 455mm axle to crown.

Want it a little more nimble - build up some 29er rims and ride some 29+ tires. This thing is AWESOME. The small weighs in at 26 pounds 6 ounces with the Maxxis tires.

Ships in 2 boxes. $50 shipping in the continental US. Additional shipping charges may apply to other areas.
