ROTOR chainring QXL ring Aero 2-LK130 Interior

The even greater in oval form of QXL Rings chainrings serves to make better use and thus increase their own performance strengths of the leg muscles! By 10% increased to 16% ovalization improves performance at each individual in dependence.

The theory of ovalization relies that the leg muscles of man is primarily aimed to straighten the leg while angling the leg is necessary only rarely and without much effort. The corresponding muscle groups are therefore less pronounced so naturally that even through hard training the performance of the different muscle groups can not be equalized to each other. From this difference, therefore, is always followed with round chainrings a non-circular passage and a significantly faster fatigue the pulling muscles while pedaling.
Rotor Q-Rings set at this point and strain due to its oval shape, the pressing muscles stronger, while reducing the pulling any muscles. This concept increased by making better use of anatomical thus both the sprint and endurance performance!

The chainrings are essentially for a plurality of holes for the chainring bolts that allow the orientation of the leaves finely tuned to your own preference adapt! The particular shape of the chainrings allows you neatly executed switching ramps precise shifting. The Aero chainrings have due to their continuous outer surface less surface for the wind and offer so again a small advantage at high speeds.
