Dura-Ace R9100 11-Speed 110mm Chainring

Shimano made waves with the Dura Ace 9000, introducing an 11-speed crankset with a 4-arm asymmetric spider that fits both standard and compact chainrings. The Dura-Ace R9100 crank continues this great tradition. Its patented Hollowglide Chainring is a game-changer - super stiff yet incredibly lightweight. It shifts better than any other chainring on the market and can handle the force from Di2 front derailleurs with ease. The forged and precision-machined alloy rings have Hyperdrive tooth profiles. These are designed for precise shifting and less wear. The chainrings are anodized to match the 9100 crank spider perfectly, giving you both great stiffness and looks. The inner and outer chainrings work as a unit, with shift ramps and pins optimized for top performance. We recommend replacing them as a set when changing sizes. They are genuine Shimano 9100 replacement chainrings, made for the Dura Ace 4-arm asymmetric spider. The Hollowglide 2-piece hollow chainring is both strong and light. Specifications include 11 drivetrain speeds, a 110 Shimano Asymmetric chainring BCD, black color, and aluminum material.

Using your Shimano Dura - Ace R9100 chainring is straightforward. Just make sure it's properly installed on your Dura Ace 4 - arm asymmetric spider. When you're riding and shifting gears, the chainring's precision design will ensure smooth and accurate shifts. As for maintenance, keep it clean. After a ride in dirty or wet conditions, use a mild cleaner and a soft brush to remove dirt and grime. Make sure to dry it thoroughly to prevent rust. When it comes to wear, check the tooth profiles regularly. If you notice significant wear, it's time to replace the inner and outer chainrings as a set, as they are designed to work together for optimal performance. Also, be careful when handling the chainring as it's made of lightweight aluminum, which can be damaged if dropped or hit hard.
