ROTOR chainring Q-Rings Aero oval double LK 110 mm | 4 hole for rotor ALDHU | Shimano GRX exterior

Rotor chainrings have been known for their high quality for many years. Now you can also install the flat Q-Rings Aero chainrings from the Spanish manufacturer on your Shimano GRX cranks. The outer chainrings with 48 or 46 teeth with an asymmetrical 110 mm bolt circle diameter should be combined with the matching inner chainrings with 31 or 30 teeth with an asymmetrical 80 mm bolt circle diameter .
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 it is based on the fact that the human leg muscles are primarily designed to straighten the leg, while bending the leg is only necessary rarely and without great effort. The corresponding muscle groups are naturally so differently developed that even through hard training, the performance of the different muscle groups cannot be adjusted to each other. With round chainrings, this difference always results in an uneven kick and a significantly faster fatigue of the muscles that pull when pedaling. The Rotor Q-Rings start at this point and, due to their oval shape, put more strain on the pressing muscles and at the same time relieve the strain on the pulling muscle parts. This concept increases both sprint and endurance performance through better use of the anatomical conditions!
The OCP system (Optimum Chainring Position) has been further refined for optimal adjustment of the oval Q-Rings. The position of the chainrings can be adjusted in 1-degree increments using a combination of different positions of the crank arms on the crankshaft and a finely ratcheted spider mount (only in conjunction with Rotor cranks ).
