Pedal Faster With Less Effort
Rotor's Aero MAS Spider is engineered to provide minimal air resistance, reduce drag and allow you to pedal faster with less effort. It is compatible with Rotor's line of modular road cranks, the ALDHU and VEGAST and 2INpower and INpower power meter crank arms. Select the perfect chainring size from 1x/2x 110x4 Q RINGS or round range from Rotor.
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.
