Road Compact and Campagnolo Compact

Meet cycling's ultimate secret weapon. Q-Rings offer some of the performance advantages of the Rotor System to those with standard cranksets without the weight penalty.

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.
