Rotor Round Road Outer Chainring Black, 50T

While rotor's ovalized Q-Rings have had proven results for many riders, some guys, even on team Garmin-Cervelo, have not made the switch. For those who prefer a round outer ring, there's the Rotor Round Outer Chainring, which is available in either a 50t/110mm or 53t/130mm size. The round rings are constructed exactly like the Q-Rings--from hard-anodized 7075-T6 aluminum with laser-etched silver graphics on the outer surface of the ring.
