ROTOR

ROTOR is a Spanish cycling component brand founded in Madrid in 1997, specialising in innovative chainrings, cranksets, power meters, and drivetrain components for road, gravel, and triathlon cyclists. Best known for their Q Rings oval chainring technology — which uses an elliptical chainring shape to optimise the power delivery through the pedal stroke — ROTOR components are trusted by professional road and triathlon cyclists who want to maximise efficiency and reduce fatigue on long rides and races. At Swinnerton Cycles, we stock ROTOR chainrings for road, gravel, and Shimano GRX drivetrain builds.

The ROTOR range includes Round Ring 1x direct mount chainrings for single-chainring gravel and road setups, and Q Rings oval chainrings in GRX-compatible BCD configurations for Shimano GRX gravel and road groupsets.
