Rotor Bike Components Hawk & Raptor crank axle Boost QF

Boost crank axle for the new R-Hawk and R-Raptor single cranksets with maximum modularity: crank axle, crank arms, and rubber bumper sets can be combined individually, 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 and R-Raptor cranks are compatible with almost all bottom bracket standards on the market and cover three different axle lengths.

The Rotor patented technology of "OCP mounting" a Q-Ring makes the difference: the individual adaptation of oval chainrings to the crank arm enables the biomechanical advantages of the system. The crank arm, spider, and direct-mount chainrings of the new Enduro cranks Hawk and Raptor can be adjusted independently thanks to Rotor's patented gearing. This allows each user to adjust their individual setup to the optimal position for them. The different positions of the "OCP Mount" technology (Optimum Chainring Position) allow an individual adjustment of the Q-Rings in up to five positions. This fine micro-adjustment is the secret for a completely individual setup of oval chainrings to the rider's needs. This makes it possible to prevent or eliminate knee problems, optimize the effectiveness of the crank rotation, or even improve traction on MTB and cyclocross. Position your chainrings with the "OCP Mount" system from Rotor to ride as efficiently as possible. OCP is only available on the Rotor Q-Rings.
