RRaptor Crank Arms - Bike Build

he R-Raptor checks all the standard boxes for an all-mountain/enduro crank. Like ROTORs REX cranks, the RRaptor is a work of engineering built on the principles of lightweight and rigid, but RRaptors modular concept offers compatibility that meets and even exceeds current trends in mountain bike technology. Crank arms will be available independent of an axle and chainrings; theres no longer a factory-assembled arm+axle, both crank arms can be removed from the axle. This way the RRaptor can be mounted to standard, boost, and downhill axles.
