The R-Raptor checks all the standard boxes for an all-mountain/enduro crank. Like Rotor's REX cranks, the R-Raptor is a work of engineering built on the principles of lightweight and rigid, but R-Raptor’s 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; there’s no longer a factory-assembled arm+axle, both crank arms can be removed from the axle. This way the R-Raptor can be mounted to standard, boost, and downhill axles.
Rubber bumpers protect crank arms against wear, and can be customized with a choice of five colors: black, blue, yellow, red, or orange. Direct Mount chainrings for the R-Raptor feature Rotor's patented Optimum Chainring Position (OCP) system to optimize your pedal stroke. Swapping out chainrings on the fly becomes incredibly easy with just an 8 mm allen key.
