Still getting more individualised: the 4-arm spider by Rotor
The ALDHU 3D+ and VEGAST cranks are Rotor's most innovative cranks ever. The innovative modular structure, together with axles and different chainring options, makes each component individually available to accommodate the current spectrum of riders and bike standards.
The ALDHU 3D+ and VEGAST incorporate OCP Mount technology, which enables the rider to fine-tune the orientation of Rotor's oval Q-Rings. Their proprietary, patent-pending design is based on the modularity of each crankset component.
Chainring Mount: 110 mm bolt circle diameter, 4-arm asymmetrical
- OCP (Optimum Chainring Position) Mount Technology for fine-tuning the orientation of Rotor's oval Q-Rings
- for chainring change only an allen key is required
Rotor's exclusive patented technology " OCP Mount" refers to the pedalling's biomechanical optimization when you are using Q-Rings; this lets you adjust the orientation between chainrings and cranks by one step degree.
The shape of the axle lets you position independently both cranks and spider or Direct Mount, and thereby change the relative orientation in order to adapt to the optimum orientation of each user.
The multiple positions offered by " OCP Mount" technology let a fine adjustment of the OCP (Optimum Chainring Position). In this way, with the OCP Mount technology, any oval chainring can benefit from an OCP with micro-adjustment to increase the performance of your pedalling and your knees health, or even to modulate the traction in MTB and Cyclo-cross.
Adjust perfectly your chainrings to your pedalling style with the Rotor's " OCP Mount" .
