Robust. Smooth. Efficient
Rotor's new 110x4 Direct Mount Spider features a cleverly designed spline interface that, when mounted to the Aldhu Spindle, delivers a robust-yet-smooth engagement allowing for the maximization of efficiency in transmission of power in the pedal rotation. Combined with Rotor's new Aldhu cranks and Q RINGS oval chainrings or Round chainrings, the innovative spider includes refined OCP Mount technology for total adjustment, finding your optimal chainring position by precise one degree increments.

A Fully Customizable Crankset Approach
Here's how Rotor's new cranksets work — everything is modular. You choose the arms, the spindle, and the chainring. And whether you want a power meter-equipped spider, spindle, crankarm, or none of that. You can even choose between round and oval chainrings. Then piece it all together to create the exact system that suits your specific needs.
