While Garmin-Cervelo's Q-Rings converts Heinrich Haussler and Christian Vande Velde win races and build form towards July aboard Rotor's non-traditional ovalized chainrings, not everyone on the team made the switch. Cameron Meyer is one rider on the team who depends on Rotor's standard round chainrings. In fact he rode them to his overall win at the Tour Down Under. These Rotor Round Road Outer Chainrings are built in identical fashion to their Q-Rings, save for the ovalized shaping. Like other high-quality chainrings on the market, they have stainless steel pins and machined ramps for superb shifting from the small ring and back.

Rotor Round Road Outer Chainrings are CNC machined from 7075-T6 aluminum, and they have a hard anodized black finish with laser etched silver graphics on the outboard side. They fit Rotor Agilis and 3D Cranksets and are also compatible with any crankset using 110 or 130mm BCD (bolt circle diameter). They're available in two sizes -- 50t/110mm, 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.

Wanting to swap out an '88 Schwinn world sport outer chainring with the 53T/130mm, possible?
