Borealis Telluride fat bike, medium, gray. Aluminum frame with carbon fiber fork, carbon bars, seat post and carbon Race Face crank arm. 12 speed Sram NX drive train with 10/52 cassette and 32T front ring. Tektro hydraulic disc, four piston brakes with 160mm rotors front and back. This bike can be set up with front suspension. 27.5" MuleFut aluminum rims with 4" 45N Vanhelga tires. These rims can easily be converted to a tubeless set up, but comes with tubes. Bike is in very good "like new" condition. It was purchased directly from the manufacturer in Colorado. Bike was demoed for sales once at an event, but never raced. Very lightly ridden! Due to the Telluride's slack frame geometry, light weight and responsiveness, its a bike for all terrains year round. Great for single track, gravel, the beach and groomed snow!
