The carbon fiber frame and fork minimize weight and maximize power transfer. The extra diameter of 27.5” wheels offers more momentum and rollover capability than 26” wheels. Frame and fork mounts for extra bottles and cargo make it easier to gear up for your long days out or even overnighters. Add Shimano’s Deore 11-speed components, and it all adds up to one of the best carbon fat tire bikes out there, whether you’re a racer or just enjoy the feel of a fast and light fat tire ride.
