ROTOR Bike Components

ROTOR Bike Components (officially ROTOR Componentes de Innovación S.L.) is a renowned Spanish manufacturer specializing in high-performance cycling components, particularly oval chainrings (Q RINGS), power meters, cranksets, bottom brackets, and drivetrains. The company was founded in Madrid, Spain, in the mid-1990s by aeronautical engineering students and cycling enthusiasts Pablo Carrasco and Ignacio Estellés, who sought to eliminate the 'dead spot' in pedal strokes with biomechanically optimized crank and chainring systems.

ROTOR designs, engineers, and manufactures its high-precision aluminum bicycle components primarily at its dedicated CNC machining and production facility located in Ajalvir, Madrid, Spain. This domestic European manufacturing approach allows the brand to maintain strict quality control and continuous development for competitive road, gravel, and mountain cyclists worldwide.

Today, ROTOR Componentes de Innovación remains an independent Spanish entity headquartered in Madrid, managing global distribution through cycling distributors and subsidiary hubs (including ROTOR UK / Velotech Services for the United Kingdom market). Although other unrelated companies share the name 'Rotor' across aviation, pump manufacturing, and industrial electronics, ROTOR Bike Components operates autonomously within the cycling industry.
