Rotor R-Hawk Crank Arms

Maximum modularity: the R-Hawk Crank by Rotor

Crank axle, crank arms and rubber bumper sets of the R-Hawk 1-speed crank 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-Hawk is compatible with almost all bottom bracket standards on the market and covers three different axle lengths.
The R-Hawk product family sets new standards in mountain bike technology and has been developed strictly according to the specifications for maximum stiffness with minimum weight. The weight of a complete R-Hawk 175 mm crankset with 30T chainring is only around 665 g.
Coloured rubber bumpers protect the crank arms from damage when off-road. The chainring can be changed out effortlessly, and the R-Hawk 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.
