The same team that brought you the Mallet and 5050 pedals have turned their attention to headsets. The Crank Brothers Opium SL Directset omits the standard headset cup and replaces it with flanges incorporated directly onto the bearing itself. This lowers the stack-hieght of the Iodine SL Directset to an industry best 21mm, an ideal match for todays long travel downhill bikes.
