Rotor
Rotor is a Spanish cycling components brand with a reputation built on precision engineering, innovative biomechanics research, and a relentless pursuit of performance. Founded in Madrid in 1999, Rotor set out to challenge conventional thinking in drivetrain design, pioneering oval chainring technology and developing some of the most advanced power measurement systems available to cyclists today. Trusted by WorldTour professionals and serious amateur riders alike, Rotor has grown into a globally respected name synonymous with quality, data-driven design, and race-proven reliability. About Rotor Rotor's product range spans cranksets, chainrings, bottom brackets, pedal-based power meters, and complete groupsets including the acclaimed ALDHU and KAPIC systems. The brand is perhaps best known for its Q-Rings — elliptical chainrings designed to optimise the rider's pedal stroke by maximising power through the strongest phase of each revolution and reducing resistance during the weakest phase. This technology, backed by extensive biomechanical research, has been adopted by professional cyclists across road, gravel, and triathlon disciplines. Why Choose Rotor? Rotor components suit cyclists who demand accuracy, efficiency, and longevity from their equipment. Whether you are a competitive racer seeking marginal gains, a triathlete chasing a personal best, or a dedicated club rider looking to upgrade your drivetrain, Rotor offers a solution engineered to elevate your performance.
