ROTOR chainring Q-Rings oval 2x LK 110 mm | 4 holes for Rotor ALDHU | Shimano Road Outer
The popular Rotor Q-Rings chainrings in a new look. The Spaniards have not only slightly changed the look, a new tooth profile now makes the chainrings compatible with Shimano HG 12-speed chains and therefore with the current Shimano 12-speed Road groupsets. With their asymmetrical 110 millimeter bolt circle, the chainrings can be mounted on Rotor ALDHU/VEGAST cranks and on all Shimano 11-/12-speed Road cranks (including Shimano Powermeter cranks).
The oval shape of the Q-Rings chainrings is designed to make optimum use of the leg muscles and thus increase your own performance! Rotor is based on the theory that the human leg muscles are primarily designed to stretch the leg, while bending the leg is rarely necessary and requires little effort. The corresponding muscle groups are therefore naturally so differently developed that even hard training cannot equalize the performance of the different muscle groups. With round chainrings, this difference always results in an out-of-round pedal stroke and significantly faster fatigue of the muscles pulling when pedaling. This is where the Rotor Q-Rings come in and, thanks to their oval shape, put more pressure on the pushing muscles and at the same time relieve the pulling muscles. This concept increases both sprint and endurance performance by making better use of the anatomical conditions!
The OCP system (Optimum Chainring Position) has been further refined for optimum adjustment of the oval Q-Rings. A combination of different positions of the crank arms on the crankshaft and a finely graduated spider mount allows the position of the chainrings to be adjusted in 1-degree increments (only in combination with Rotor ALDHU Spider).
