Shimano Dura-Ace CN-9000 Bicycle Chain - 11 Speed 116 Link Customer Reviews

Improved chain

Standard new chain. What else is there to say except now it's not directional. It's thinner and lighter. I break a chain once every 5-10 years and I am irresponsible about changing them. Unlike the guys who change a chain every 6 months or 2-3000 miles I just keep running these things unless the shifting deteriorates or it breaks. Hopefully this will be as durable as the prior iterations. No problems in the first 2800 miles so far under race conditions with 700,000 feet of climbing so far this year.
