Shred????you don?t usually take advice from the office recycling bin but your favorite trail begs to be ridden so you obey.

QX2 chainrings for your double 110/74BCD cranks feature subtle 10% ovality that can be dialed in to take advantage of the most-powerful part of your pedal stroke to give you faster acceleration and better traction on whatever terrain you thrust under your wheels.

QX2 rings give you 3 Optimum Chainring Positions (OCP), which can be adjusted to take advantage of your pedal stroke's most-productive zone to propel you forward on each rotation.

Q-RING ADVANTAGES:
Many professional riders have successfully used oval chainrings for years and know about Q-Rings??advantages. Here you will find information about ergonomics, the science behind oval chainrings, and you will learn about some of the pros??experiences from a road, triathlon or MTB perspective.

  • Q-Rings improve your performance, minimize fatigue and reduce stress on the knees
  • Q-Rings virtually decrease the gear ratio in the dead spot and increase the gear ratio in the power phase where the rider exerts the most force
  • Q-Rings are available for nearly all standard cranks on the market
  • Q-Rings are quick and easy to mount with up to 5 different Optimum Chainring Positions (OCP)
  • Q-Rings have already played a part in many Tour de France, Giro d???Italia, Vuelta a Espaâìa, Ironman, Challenge and UCI MTB World Cup victories
  • Q-Rings are CNC-machined and produced exclusively in Spain

SOUNDS FAMILIAR, ISN???T THAT LIKE BIOPACE?
There are significant differences between Q-Rings and Shimano???s Biopace, which was well-known in the 1980???s/1990???s. ROTOR Q-Rings simulate a higher gear at the point of maximum force, i.e. the most productive part of the pedal stroke, and therefore leverage the power phase (Fig.1). In the pedal rotation???s dead spot (Fig.2), where we exert the least force, a simulated smaller gear enables us to more easily overcome this dead spot. With Biopace, it was exactly the opposite. In addition, Q-Rings feature up to 5 Optimum Chainring Positions (OCP) that can be oriented around a cyclist???s distinct pedaling characteristics.

OCP- Optimum Chainring Position
Optimum Chainring Position (OCP) represents the different setup positions that ROTOR Q-Rings offer to fit a rider???s distinct pedaling style. Q-Rings feature up to 5 OCP?s, with OCP 3 as an intermediate starting point, all to optimize your pedaling style. You can determine your OCP if you know your Optimum Chainring Angle (OCA), which can be found by conducting a TORQUE 360 pedal analysis via ROTOR?s 2INpower and INpower User Software.
