ROTOR chainring Q-Rings oval 2-fold LK 110 mm | 4 hole for rotor ALDHU | Shimano Road outside

The popular oval Q-Rings chainrings for Rotor's ultra-light ALDHU aluminum cranks. With a bolt circle diameter diameter of 110 millimeters and the asymmetrical 4-arm mount , the chainrings are also compatible with the current Shimano Ultegra and Dura Ace cranks

The oval shape of the Q-Rings chainrings is used to optimally use the leg muscles and thus increase your own performance! The theory behind this is based on the fact that the leg muscles of humans are primarily geared towards stretching the leg, while bending the leg is rarely necessary and without great effort. The corresponding muscle groups are therefore naturally so different that the performance of the different muscle groups cannot be brought into line with one another even through hard training. With round chainrings, this difference always results in an out-of-round step and significantly faster fatigue of the muscles pulling when pedaling. The Rotor Q-Rings start at this point and, due to their oval shape, put more stress on the pressing muscles and at the same time relieve the pulling muscle parts. This concept increases both the sprint and endurance performance through better use of the anatomical conditions!

The OCP system (Optimum Chainring Position) has been further refined for the optimal setting of the oval Q-Rings. Using a combination of different positions of the crank arms on the crankshaft and a fine-grained spider mount, the position of the chainrings can be adjusted in 1-degree steps.
