HAWK and Raptor crank arms are available with or without an axle; there’s no longer a factory-assembled arm+axle and both crank arms can be removed from the axle.
This allows the HAWK and Raptor to be mounted to standard, boost, and downhill axles.
MTB Standard: 142mm Rear Axle
BOOST: 148mm BOOST Rear Axle
DH: 157 Rear Axle
