More product description: - Ramping and pinned to radically improve shifting. Chains and chainrings Chainrings 135 mm. , How to reach us Harris Cyclery. 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. The ROTOR Q-RINGS are different from these two types, and all other previous types inasmuch as Q-RINGS:. 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). B) Q-RING provide a smooth rhythmic pedaling motion instead of the high-gear-low-gear feeling and high accelerations at the dead spots. entry in Sheldon Brown's Bicycle Glossary.
