Studio : Cyclone Bicycle Publisher : Cyclone Bicycle Binding : Sports Product Description Descended from the BlackBox crank used by 2009 World Champion Steve Peat. Truvativ's downhill-race specific crank uses the same forged AL7050 material as in the freeride/DH Holzfeller, but in a second-shaving 822g package (that's 240g less than the Holzfeller OCT). Does not include bottom bracket. 0
