Rotor in the round.

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.

  • CNC-machined 7075 aluminum
  • Laser-etched silver graphics
  • 50t/110m or 53t/130mm

What would be the separate weights of the 50T and 34T chainrings, respectively? Thank you.

Separately place your chain rings in clean plastic bags and find a store of some kind that has an ounce scale. When the opportunity arises place your

chain rings on the scale. This will put you on the pathway that will give you some idea about chain ring weight. This

procedure works with running shoes too.
