9-speed drivetrains put narrower tolerances on chain design than anything that came before, which is why Campagnolo engineered the Record C9 specifically for Ultra-Drive sprockets rather than adapting an older design. The chrome-nickel links get a PTFE coating that reduces friction at the roller-to-sprocket interface, and each link is shaped and beveled to match the tooth profiles on Ultra-Drive cassettes. That's where the efficiency gains come from—the chain and sprocket work as a matched system rather than as separate components.

The Perma-Link connection system uses a special pin that floats within the link plates during operation, which Campagnolo calls "Floating Link Action." This design allows the chain to articulate smoothly as it moves through the derailleur pulleys and wraps around different-sized sprockets. The anti-friction coating extends chain life by reducing metal-on-metal wear at the contact points, and it keeps the drivetrain quieter under load. You'll notice the difference most on long climbs where you're holding steady power in the same gear.

The chain ships with 114 links and includes the connecting pin for installation. It measures 6.8 millimeters wide, which is the standard width for Campagnolo's 9-speed system. If you're running older 8-speed Campagnolo components, this chain works with those drivetrains as well—the width and pin spacing are compatible. The PTFE finish gives the links a silver appearance that stays consistent as the chain wears, so you won't see the kind of color changes you get with some other surface treatments.
