Subject: ROTOR Q Rings, 53/39 T - SOLD ROTOR Q Ring Chainring Set, 53/39T - 130BCD. Good condition, very light use & low miles. Q Rings maximizes overall pedal stroke, while minimizing lactate build up. Upgraded to AERO Q Rings shortly after purchasing these (Performance from Q to Aero Q rings was negligible, purely aesthetics! ). $150.00 shipped CONUS.
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 50T Q-Ring, around the upper dead-spot is equivalent to a 48T, but as the pedal goes down and more strength is applied, the equivalent chainring tooth size reaches 52T.
