Oval chainrings compatible with the new ALDHU cranks, ROTOR's lightest crankset ever, but also compatible with 4-bolt Shimano® cranks. When mounted to ROTOR's ALDHU 3D+ cranks, these Q RINGS can be adjusted in 1-degree increments.

When mounted to Shimano® cranks, the chainrings are set to intermediate position OCP3, which is the position most frequently used by road riders. For a perfect aesthetic integration with Shimano® cranks, there is a set of bolt covers for the different crank models.

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 España, Ironman, Challenge and UCI MTB World Cup victories

-Q-Rings are CNC-machined and produced exclusively in Spain

OCP

-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.
