Rotor Q-Rings

ROTOR Q-Rings

Oval Q-Rings from ROTOR for triathlon, road, cyclocross and mountain biking make your spin cycle smoother, make climbing easier on the legs and help reduce the build up of lactates during hard efforts. Pro athletes who have chosen to ride them have put to rest any doubts about their performance by winning two grand tours, more than 25 Ironman races and over 20 UCI elite Road, MTB and CX world champion titles.

Q-Rings fit most manufacturers cranks.

HOW IT WORKS

ROTOR Q-Rings help eliminate the dead spot in your pedal stroke reducing its negative effects, moving the legs easier through the dead spot imitating a smaller circular chainring. This enables the legs to remain in the power stroke for a longer period of time when compared to round chainrings. Q-Rings change the equivalent tooth size by decreasing it before the dead spots and increasing it when the rider is in the power mode (when more power is available at the pedal down stroke).

A 53T Q-Ring, around the upper dead spot is equivalent to a 51T, but as the pedal goes down and more strength is applied (just passed the maximum power moment), the equivalent chainring tooth size reaches 56T.


FEATURES AND BENEFITS

OCP (Optimum Chainring Position), a ROTOR patented feature is the secret to success, where others have failed. The OCP system allows you to choose the angle where you obtain the maximum gear ratio, customising pedaling to each and every cyclist, where it is needed most. Since the maximum power moment is different for every cyclist (performance is different depending on pedaling style and position on the bike), the OCP System customises the ROTOR Q-Rings to your geometry and cycling habits, and takes maximum advantage of alternative leg inertias on every pedal rotation. OCP is ROTOR Q-Ring's bio-mechanical key!


ABOUT Q-TECHNOLOGY

Lightweight & Quality: CNC machined from the highest quality aluminium, with a special nickel plated finish for extreme wear resistance.

Latest technology with simple mechanics: Q-Rings are user friendly; easy to install and easy to find and change the regulation setting through the patented OCP System.

Designed and patented by ROTOR: Innovation and performance through engineering at the service of the cycling community. Fits most road or mountain bikes: Q-Rings are available in the following ratios:


What is the difference between Q-RINGS and other non circular chainrings?

The design of Q-Rings comes from ROTOR cranks biomechanical technology more so than from any previous oval or asymmetrical type chainring. Non circular chainrings have been available in various shapes since the late 1890s. All of them attempted to avoid the negative affects of the dead spot. The most recent models that are well known are the Shimano Bio-Pace and the O.SYMETRIC "Harmonic".

ROTOR Q-Rings are different from these other oval chainrings, and all other previous types because:

  1. Q-Rings take into consideration the forces from your legs in static conditions in addition to the inertia of the bicycle, the rider and the legs of the rider.
  2. Q-Rings provide a smooth rhythmic pedaling motion instead of the high-gear-low-gear feeling and high accelerations at the dead spots.
  3. Q-Rings position the equivalent high gear about 20 degrees past the power-side-crank's horizontal position, which is the approximate place where you can obtain the maximum benefit of the higher gear.
  4. Q-Rings have the OCP (Optimum Chainring Position) enabling you to customise (fine tune) the position of the chainring for your personal riding habits and riding position on the bike.
  5. Q-Rings mitigate pain and damage to the knees that is usually caused by the dead spots; if your knees feel pain they cannot deliver maximum power; when the pain is removed, your performance will clearly increase.
