ROTOR chainring Q-Rings SRAM QX2 2x LK 80 internal

The new Rotor chainrings not only impress with an aero design and the associated higher stiffness but also have a lower weight. Simultaneously, the climbing aids and teeth have been revised so that under load and also in muddy conditions a high switching performance is assured.

The oval shape of the Q-Rings chainrings serves the best use of leg muscles, thereby increasing their own performance! The theory behind this is based the fact 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 OCP system a very fine adjustment of the 4-arm crank is possible. Instead of a bore when OCP System 3 holes lined up. Thus the chainring can be optimally adapted to the own Tretgewohnheiten and seating position.
