Afterburner Double


With hollow forged arms and a forged 7050 spindle, the Afterburner double crankset represents cutting edge aluminium technology. The double chainring version is available with five chainring combinations, so there’s one to suit any kind of riding style or wheel size. Everything from 29er XC racer to 650b all-mountain is covered. All rings are stamped from hard-wearing 7075 aluminum and carry ramps and pins for slick shifting even under load. With BB30 and MegaExo versions, there’s an Afterburner to fit nearly any bike.
