|Campagnolo's top racing chain for all Campy 11 speed groupsets. Ni-PTFE Finish reduces friction for smooth pedaling, quiet operation, and greater efficiency. Ultra-Shift chain links are designed for maximum performance in Campagnolo drivetrains. Comes with Ultra-Link chain link locking system (requires either Campagnolo CN300 chain tool #2503 or Park's CT-4.2 and CT-11 [#2433 and #2434]), or you can use a Superlink (#0340). 114 links.
LickNotes: Campagnolo officially recommends replacing your 11 speed chain every 1000-2000 miles, no matter the wear. We're leaning towards fewer miles due to the increased cost of replacing cassettes, chainrings, and pulleys. Do your best to keep your chain well lubricated and as clean as is practical.
