Rotor Q-Ring Chainring

The thoughts behind Rotor:
The thoughts behind the Rotor Q-Ring chainring are clear: each pedal movement has a 'dead center'. This is the moment when your cranks sit vertically. At this point there is no possibility to keep pressure on your crank/pedals what makes you get beyond this point as fast as possible. Rotor Q-Rings have less teeth on its dead center what makes you go faster past this point. The next thing that happens is that you feel maximum resistance, at this point you can get maximum power out of your rotation. By this theory you will pass your dead center faster what ensures less power loss before you point of maximum power. This allows an efficient pedal movement which creates less lactate and fatigue.

The technology behind the rotor is characterized by efficiency. Rotor believes in fact that its products are initially not so much 'faster' but it's mostly the efficient pedal movement what the actual net time improves, this means your time trial time will be faster.

Several scientific studies have proven the positive effect of Rotor Q-Rings chainRings. Perhaps even the best proof is the many victories achieved in the pro peloton on Rotor Q-Rings / QXL-Rings.

Note: the Rotor chain rings have a fixed combination: the 53T outer chainring can only be used with the matching 39T and 38T Rotor inner chainrings and vice versa. The other fixed combinations are 50T with 34T, 55T and 54T with 42T, 54T and 53T to 44T and 50T with 36T
