ROTOR AERO OVAL Q RING BCD110x4 53T(39) OUTER BLAC

ROTOR Oval Chainrings Q RINGS® Aero 2X BCD110x4 11s. Q RINGS® BCD110x4 oval chainrings are compatible with all ROTOR cranks using BCD 110x4 spider or INspider® power meter. In addition, these chainrings are also compatible with Shimano® Dura-Ace® FC-9100 and Ultegra® FC-8000 cranks offering fast and precise shifting, attractive weight, as well as a more aerodynamic and aggressive aesthetic.

QRINGS® oval chainrings optimise pedalling by reducing dead spots and making better use of the phase of greatest force, achieving a smoother and more efficient movement. This can translate into better power transfer on climbs and sprints, less muscle fatigue and greater comfort for the knees. In addition, they incorporate the OCP (Optimum Chainring Position) system, which allows the position of the chainring to be adjusted according to each cyclist's pedalling style.

The OCP can be calculated precisely from the data provided by a ROTOR power meter, helping to maximise performance customisation.

These chainrings are manufactured and designed in Spain from 7075 T6 aerospace-grade aluminium to improve pedalling efficiency, reduce weight and decrease wear on the chainring teeth.

When you are looking for speed, precision, and aerodynamics, your bike´s components of your bike should reflect these needs.
