Shimano Dura-Ace CN-HG901 11-Speed Chain | Fits Dura-Ace R9100

This super-narrow and lightweight 11-speed chain features an HG-EV symmetrical design, ensuring smooth gear shifts and top-notch durability. The outer plate design minimizes the risk of chain suck.

The links are zinc-alloy plated, and it uses a hollow pin to reduce weight. The inner plate is engineered for better gear contact, enabling smoother shifting under heavy loads, efficient pedaling, increased stiffness, and near-silent performance. It has a 5.62 mm chain width, perfect for 11-speed Super Narrow HG-EV drivetrains. It comes with a Quick Link for fast, tool-free chain assembly. With an average weight of 243 grams, it's a great choice for cyclists.

Using this chain is easy. First, if you're replacing an old chain, remove it from your bike. Then, attach the new chain using the included Quick Link. No tools are needed, so it's a quick process. When riding, you'll notice smooth and efficient gear shifts. For maintenance, clean the chain regularly with a bike cleaner. Make sure to dry it thoroughly to prevent rust. Lubricate the chain after cleaning to keep it running smoothly. Also, check the chain for any signs of wear or damage. If you notice excessive wear or if the chain is damaged, it's time to replace it. Keep in mind that proper installation and maintenance will ensure the chain performs well and lasts a long time.
