Rotor Spider Gravel - BCD110/80x4 | OCPmount - gloss black

The ROTOR BCD 110/80x4 Gravel spider features cleverly designed gearing when mounted on the crank spindle that allows for robust yet smooth engagement so you can maximize the efficiency of power transfer in your pedal stroke.

When combined with ROTOR VEGAST® / ALDHU® cranks and Q-RINGS oval chainrings or round chainrings, the innovative spider incorporates refined OCPmount technology that allows you to adjust your optimal chainring position in precise 1-degree increments.

Use the unique OCP to unleash a more efficient pedal stroke, reducing knee strain and potential injury. The improved 12.5 percent ovality increases your performance benefits by providing full activation of muscle groups, generating more power and reducing long-term stress on the knees.

Compatible with ROTOR ALDHU, ALDHU24, VEGAST, VEGAST24 and INpower DM Road cranks.
