Increased speed, reduced consumption
- Q-Ring sprints were faster (-1.6 sec & 0.7 kph-1.8%) and generated more power (+26.7W-6.2%)
- Reduced oxygen consumption and heart rate.
Q-RINGS INCREASE PERFORMANCE
Your effort has its payoff
- Immediate performance increase on switching from round rings to Q-Rings. And vice-versa.
- It also appears that the more effort a cyclist exerts, the greater the benefit of Q’s.
Q-Ring-Round Ring Comparison
Far from feeling unusual, a Q-Ring feels much rounder than a round ring. A spinscan analysis visualize a cyclists power delivery, with a bar graph indicating the variation from maximum to minimum output and a polar graph showing the rotating shape of the power profile. By comparing the left hand Round chainring spinscan and the right hand Q-Ring spinscan below, one can see that Q-Ring graphs are clearly smoother (less variation in torque in the bar graph) and fuller (less of a peanut shape at the weakest point).
When one projects a polar plot of a typical spinscan over the varying drivetrain resistance of a 53t Q-Ring during its rotation, the value of a Q-Ring is clearly visible: Maximum power is met with a “56,5t” Time trial sized chainring diameter and minimum power is met with a “50,4” compact size chainring diameter. This variation creates the “perfect spin” we all aspire to, that simply isn’t possible with round chainrings. This is because Q-Rings compensate for the weakest zone of the pedalling stroke and maximize use of the most powerful zone.
Optimum Chainring Position
You can micro adjust the position of your Q rings to suit your riding style. Q-Rings use your leg muscles at a different rate than round rings, thereby changing your intramuscular coordination of motor units. Thanks to the OCP (Optimum Chainring Position) of the Q-Ring, you will find your best position seeking both comfort and efficiency.
A standard crank in combination with the OCP of the Q-Rings, allows approximately 5 degrees of adjustment. The MAS spider offers half positions giving approximately 2,5 degrees (for more information on the MAS, click the link below).
Pedal comfortably in all cycling positions
The OCP (Optimum Chainring Position) of the Q-Ring allows you to pedal comfortably in all cycling positions:
