SHIMANO Dura-Ace 9000 Chainring

The Shimano Dura-Ace groupset is well known for its precision engineering. This engineering extends into every part of the groupset, including the new 9000-series Chainring. The DA 9000 chainring is made from alloy that has been carbide-reinforced. Carbide is often used in drill tips for longevity and durability, and you'll find those same qualities extend to the chainring. Additionally, the teeth on the rings receive less wear, making for consistent, smooth shifting. But, as perfect as these chainrings are, they are only compatible with Shimano -Speed road drivetrains.
