ROTOR 110×4 Spider

The ROTOR 110×4 Spider, which can be used with ROTOR’s ALDHU or VEGAST cranks or with the 2INpower and INpower DM Power Meters, allows you to run your choice of ROTOR 110×4 chainrings. The ALDHU spider features a spline interface that mounts directly to the axle. The spider also includes refined Optimum Chainring Position (OCP) Mount technology. This allows you to adjust your chainring position in precise, one-degree increments.
