Rotor Q-Rings Sram XX MTB Chainring (Oval) Outdoor 4x120mm BCD

Oval chainrings Qrings – center distance 120/80 (Sram) Internal 80, specific model for Sram cranksets center distance 120/80, including Sram XX .
The “Aero” design of the chainrings provides great rigidity with a very competitive weight. The oval Q-Rings chainrings reduce the detrimental effect of the neutral point thanks to their oval shape.
Why use round chainrings when the force that we are able to apply on a pedaling cycle is not constant?
When the neutral point arrives, the crown is then on its smallest diameter thus making it possible to pass it more easily, more quickly and with more flexibility.

As soon as you pass neutral in the pedaling cycle, the diameter of the Q-Ring gradually increases, until it exhibits the greatest development when your muscles can deliver their maximum power. Oval crowns already tried to make their way a few years ago and were widely criticized, but don’t be fooled: the Rotor concept is the exact opposite of its oval ancestors.

Indeed, among the old oval chainrings some offered the maximum leverage at the moment of neutral (this concept only increased the stress on the muscles and was therefore the reverse of ROTOR’s QRINGS technology). The shape of the oval Q-Rings plates is particularly studied.
Qrings will allow you to gain power, endurance, motor skills and reduce joint stress on your joints. The results have already convinced a good number of practitioners: more natural pedaling, less fatigue at the end of the race, less traumatized muscles, it’s up to you to try …
