Shimano Dura-Ace R9100 Chainring

This chainring is specifically designed for the Shimano Dura-Ace R9100 series cranksets. It uses a 110mm BCD with a 4-bolt mounting pattern, so it will not fit older 5-bolt cranksets or non-Shimano systems.

No, this chainring is engineered exclusively for 11-speed drivetrains. Using it with a different speed setup will likely cause shifting issues and premature wear on your chain.

The hollow design removes unnecessary material to save weight without sacrificing the rigidity needed for power transfer. This ensures that when you put power into the pedals, the chainring doesn't flex, keeping your shifting crisp and efficient.

No, this is a replacement chainring only. You will need to reuse your existing chainring bolts or purchase a new set separately if your current ones are damaged.

This is an outer chainring with 53 teeth. It is designed to be paired with a compatible inner chainring to complete your crankset setup.
