Rotor Aero Q Outer TT Chainring 130 BCD 5 Bolt
This chainring will increase your power whilst reducing the time you are in the weakest zone “dead spot”. When one projects a polar plot of a typical spinscan over the varying drivetrain resistance of a 53t Q-Ring during its rotation, the value of a Q-Ring is clearly visible: Maximum power is met with a “56,5t” Time trial sized chainring diameter and minimum power is met with a “50,4” compact size chainring diameter. This variation creates the “perfect spin” we all aspire to, that simply isn’t possible with round chainrings. This is because Q-Rings compensate for the weakest zone of the pedalling stroke and maximize use of the most powerful zone.
