Rotor R-Raptor Crank with Boost Crank Axle

Maximum modularity: the R-Raptor Crank by Rotor

Rotor R-Raptor is a 1-speed crank with maximum modularity: crank axle, crank arms and rubber bumper sets can be individually combined; perfectly complemented by a wide range of Direct Mount chainrings in the oval Q-ring variant or alternatively as round noQ-rings. The R-Raptor is compatible with almost all bottom bracket standards on the market and covers three different axle lengths.
The R-Raptor product family has been developed according to the same design criteria as the R-Hawk, but is CNC-milled from 6082 aluminium and is therefore slightly heavier. The weight of a complete R-Raptor 175 mm crankset with 30T chainring is around 715 g.
Coloured rubber bumpers protect the crank arms from damage when off-road. The chainring can be exchanged effortlessly, and the R-Raptor can thus be adapted to different operating conditions. All that is required is an 8 mm hex tool.

Technology:

OCP Mount
The exclusive Rotor technology OCP Mount stands for biomechanical optimisation of the pedal stroke when using Q-Rings. OCP Mount allows you to adjust the alignment of the chainring on the crank in 1 degree increments. The shape of the axle allows independent positioning of the crank arms and Spider or Direct Mount chainring, changing the relative position so that the optimum setting can be found for the user.
The multiple positioning possibilities of OCP Mount allow a super fine adjustment of the OCP (Optimum Chainring Position). This makes it possible to prevent or eliminate knee problems, to optimise the effectiveness of the crank rotation or to improve the traction on the MTB and cyclocross.
Position your chainrings with Rotor's OCP Mount System to get the most out of your ride.
