Rotor

Rotor is the Spanish company that built its entire philosophy around one engineering problem — eliminate the dead spot in the pedal stroke. The Rotor collection at RA Cycles covers the full range of their componentry: Q-Rings (oval chainrings designed to load force through the stroke’s power phase and ease off at top and bottom dead center), alongside NoQ round chainrings, 3D+ cranks, FLOW Aero cranksets, and three tiers of crank-based power meters. The INPower measures left-leg power from a single-sided crank; the 2INPower captures both legs independently for a true dual-sided picture. Whether you’re adding a Rotor power meter to an existing build or upgrading to the OCP-adjustable Q-Ring system, this collection covers it — over 100 products across road, MTB, gravel, and triathlon applications.
