ROTOR chainring Q-Rings Aero oval double LK 110 mm | 4 hole for rotor ALDHU | Shimano Road Outer for Flattop AXS
The aero version of the popular oval Q-Rings chainrings for the Rotor ALDHU Carbon, ALDHU 3D+ and VEGAST cranks . With a bolt circle 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 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 pushing 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.
NOTE: The chainring is only compatible with SRAM Flattop 12-speed chains for SRAM AXS road bike drives.
