The new Mach 6 brings the benchmark stability and enduro performance of our 29” Firebird and infuses it with the unbridled fun that only 27.5” wheels can generate. The Mach 6 blends these seemingly contradictory traits together into a true do-it-all superhero; a bike that is at home everywhere from the sculpted hits of park riding to the burly chunk of the untamed backcountry.
