Rotor
Direct Mount 2x Chainring Set

Optimum Chainring Position Tech With 12.5% Ovality

Rotor's Aldhu Q Spidering Oval Direct Mount Chainring Set features patent-pending, proprietary technology that allows the oval Direct Mount to be adjusted in 1-degree increments for optimized pedaling biomechanics. 12.5% ovality heightens the performance advantages of oval chainrings. Rotor claims that no other oval chainring on the market offers the adjustment options plus unique ovality.

Crankarm Compatibility:

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.
