These Rotor Q-Rings feature a subtle yet efficient 10% ovality which can be user adjusted to take advantage of your full pedal stroke potential. Aero in design, they are available as outer rings only (black or red), in various sizes & BCD fitments.
Oval chainrings featuring subtle but efficient 10% ovality where the smallest diameter is at the weakest point of the pedal stroke and the maximum diameter at the strongest point of the pedal stroke. Q-Rings offer 5, sometimes 4 or 3, Optimum Chainring Positions (OCP) that can be adjusted to take advantage of the pedals stroke's most productive zone. Q-Rings are ideal for riders trying these rings for the first time and getting the correct setup can take a short period of time. Would advise newbie users of Rotor Q-Rings to take careful note of setup and also NOT to try the QXL chainrings as these are designed for specific riders and riders with lots of experience in using Q-Rings.
Please see the compatibility chart to determine if these chainrings are compatible with your crankset model.
Note: These chainrings are compatible with 5-Bolt cranksets from SRAM, FSA and 130mm B.C.D. Shimano.
