Since 2013, Borealis has specialized in lightweight carbon fiber fat bikes. The tried and true Crestone is their flagship model, with clearance for up to 5” wide tires. Very light and nimble, the Crestone is also built to take whatever comes its way.
These Crestones are equipped with a wide-range SRAM Gx Eagle drivetrain, SRAM Level brakes, lightweight Mulefut alloy rims, carbon seatpost and handlebars, and either Schwalbe Jumbo Jim or 45NRTH Vanhelga tires. We also set these up tubeless so you don't have to! Now through the end of the year we're offering these beauties for $1000 off while supplies last.
