Road    Chainrings

Rotor Q-Ring Outer Chainring

The slightly ovalized 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). This brilliant design helps reduce the dreaded dead spot's negative effect by moving the legs easier through the dead-spot imitating a smaller circular chainring and enabling the legs to remain in the power stroke for a longer period of time when compared to round chainrings. Another feature of the Q-rings is that the position of the power portion of the chainring can be adjusted for optimal power and feel.

Select 130mm for 130mm bolt circle cranks or 135mm for Campagnolo 135mm bolt-circle cranks. The 135mm Campagnolo fits old square taper cranks and new UltraTorque cranks. The 135mm will work with 2011+ Campy UT cranks with the use of optional Rotor KCNC Chainring bolts sold separately.
