Shimano Dura-Ace 9000 Chainring

This chainring is designed specifically for the Shimano Dura-Ace 9000 series 4-bolt cranksets with a 110mm bolt circle diameter (BCD). It is not compatible with older 5-bolt designs or non-Shimano cranksets.

No, this chainring is optimized specifically for Shimano 11-speed drivetrains. Using it with other speeds may compromise shifting precision and lead to premature wear.

Hollowglide technology uses a hollow construction to significantly reduce the weight of the chainring without sacrificing stiffness. This ensures your power transfer remains efficient while keeping the overall weight of your bike down.

This is an outer chainring, designed to be paired with an inner ring to complete your drivetrain setup. It features specific ramp and pin profiles to facilitate rapid, crisp shifting from the inner ring to the outer ring.

No, this product includes only the chainring itself. You will need to reuse your existing 4-bolt hardware or purchase a compatible bolt set separately.
