Rotor Q Ring Outer Aero Chainring 130BCD
Rotor Q-Rings increase your power by emulating a Rotor System crankset in the power stroke and by minimizing the intensity of the "dead spot" zones. By extending the time you spend in the power stroke (where 90% of all power is produced) and smoothly accelerating the legs through the critically weak "dead spots".
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, the equivalent chainring tooth size reaches 56T.
