Shimano Dura-Ace R9100 Chainring

No, this chainring is specifically engineered for 11-speed road drivetrains. Using it with other speed systems will likely result in poor shifting performance and potential drivetrain damage.

Yes, it uses a standard 110mm bolt circle diameter (BCD) with a 4-bolt mounting pattern, which is the standard for the Dura-Ace R9100 series. It is designed to fit seamlessly onto compatible Shimano road cranksets.

Hollowglide is a hollow construction technique that removes excess material to save weight without sacrificing stiffness. This rigidity ensures that your power is transferred efficiently to the drivetrain, especially during hard efforts.

No, this is strictly an inner chainring. The ramp and pin profiles, as well as the physical shape, are specifically designed for the inner position to facilitate smooth shifting from the small ring to the large ring.

While it is optimized for Shimano 11-speed chains, it will generally function with other high-quality 11-speed chains. However, for the most precise shifting and longest component life, using a Shimano-compatible chain is recommended.
