Rotor Q-Ring 130*5 Klinge

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 a efficient pedal movement which creates less lactate and fatigue.

The Rotor Q-rings 130*5 will fit almost all the cranksets with a 130 mm spider. These chainrings won't fit Sram Hidden-bolt cranksets.
