Shimano Dura-Ace 9000 Chainring

No, this chainring is specifically engineered for 11-speed drivetrains. Using it with a 10-speed system will likely result in poor shifting performance and potential chain drop.

This chainring uses Shimano's proprietary Asymmetric BCD pattern. While it measures 110mm, it is designed specifically for Shimano Dura-Ace 9000 series cranks and will not fit standard 110mm BCD cranksets from other manufacturers.

No, this is specifically designed as an outer chainring. The ramp and pin profiles are optimized for shifting from the inner ring to the outer ring, and the mounting interface is not compatible with the inner position.

Shimano often uses stock photography for component listings. The item you receive will be the correct Dura-Ace 9000 outer chainring, but the specific tooth count or finish details may vary slightly from the representative image shown.

While it is designed for the Dura-Ace 9000 series, it can technically be mounted to other Shimano 11-speed cranks with the same Asymmetric BCD. However, for the best shifting performance and aesthetic match, we recommend sticking to the chainrings designed for your specific crank model.
