, Dura Ace FC-R9100, 52T Chainring, MT, 11sp, BCD: 110, Aluminum, Black

This Shimano outer chainring is designed to update or maintain the high-performance Dura-Ace FC-R9100 11-speed crankset. Specifically engineered for a 52/36 tooth combination, it allows riders to optimize their gearing for a balance of high-speed descending and efficient climbing. The 4-bolt design utilizes a 110mm asymmetric BCD to ensure a perfect fit and seamless integration with the R9100 crank arms.

The chainring incorporates Shimano Hollowglide technology, a high-rigidity hollow structure that significantly reduces weight while increasing overall strength. This reinforced construction minimizes flex under load, providing superior power transfer and the quick, precise front shifting performance expected from the Dura-Ace series. It is a vital component for maintaining the elite drivetrain standards of professional-level road cycling.
