Rotor Gravel Spider, 4-arm, 110/80 mm Bolt Circle Diameter

Rotor Gravel Spider for Shimano GRX bolt circle diameters of 110 mm and 80 mm

The Gravel Spider from Rotor has four asymmetrically arranged arms and is designed for mounting large chainrings with a 110 mm bolt circle diameter as well as small chainrings with an 80 mm bolt circle diameter. This bolt circle combination is characteristic for cranks of the Shimano GRX groupset and is therefore also present in gravel-specific chainrings from Rotor. The spider has the special OCP Mount toothing, which allows fine adjustment of oval chainrings in 1 degree increments when using a matching axle. This way you can benefit from the advantages of the Rotor OCP mount technology even if you ride with a Shimano GRX derailleur.

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 for the user can be found.
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 ride as efficiently as possible.
