Rotor Q-Ring Aero 54T 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.

    WOW! These DO make a difference! I borrowed a bike from someone who had this ring on it in the 54 tooth design. No problem what-so-ever with shifting in front and a huge advantage over conventional chainrings in a time trial!
