These Rotor Round Road Inner Chainrings are made just like Rotor's ovalized units, though they stick to the traditional round geometry that most folks are used to. And as much as we like Rotor's non-traditional Q-Rings, the reality for many riders is that they prefer round rings, or are hesitant to try ovalized rings since they don't have physical issues that stem from their use of round rings. Garmin-Cervelo's Thor Hushovd is a classic example. He won his World Championship on Rotor 3D Cranks fitted with Rotor's round chainrings.

Rotor Round Road Inner Chainrings are CNC machined from 7075-T6 aluminum, and they have a hard anodized black finish. 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 three sizes -- 34t/110mm, 39t/130mm, and 44t/130mm.
