Q-Rings have been used in mountain biking for some time now, they have many benefits especially when climbing, as they cut fatigue in your legs and help provide extra grip due to the smoother torque output. On loose terrain, this can be the difference between riding or pushing up! Marathon, XC riders, Enduro and downhill riders can all enjoy those benefits now.
Q-Rings make your spin cycle smoother, make climbing easier on the legs and help reduce the build up of lactates during hard efforts. Pro-riders tell us they are great for stage racing and blocks of training. Please download and read this 'guide to adaptation' before proceeding to buy Q-Rings.
ROTOR Q-Rings minimise the dead spots like reducing the size of a regular chainring, and give you more time during the pedal down stroke. This allows for a lower physical demand on your body, so you are able to ride longer with less fatigue, climb easier…
ROTOR Q-Rings do not eliminate the dead-spot (as do Rotor Cranks) but help to reduce its negative effects, moving the legs easier through the dead spot imitating a smaller circular chainring, and enabling 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.
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!
Lightweight & Quality: CNC machined from the highest quality aluminium, with a special nickel plated finish for extreme wear resistance.
Latest technology with simplest mechanics: Q-Rings are user friendly; easy to install and easy to find and change the regulation setting through the patented OCP System. Affordable: prices are within the reach of every cyclist.
Designed and patented by ROTOR: Innovation and performance through our engineering at the service of the cycling community. Fits most high-end bikes: Q-Rings are available in the following versions:
(Other Q-Ring sizes will become available in the future).
The design of Q-Rings comes from ROTOR crank's 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".
