Chain friction costs you watts on every pedal stroke, which adds up over a ride when energy moves through the drivetrain thousands of times. This Record-level 11-speed chain uses hollow pins to reduce weight compared to solid-pin designs, and the nickel-PTFE surface treatment creates a low-friction interface at the roller-to-sprocket contact points. The coating reduces the drag that develops when metal surfaces slide against each other under load, which keeps more of your pedaling effort moving the bike forward rather than generating heat in the drivetrain.

The chain measures 5.5mm wide, which accommodates the narrower spacing required for eleven sprockets on a standard cassette body. The outer plates use chamfered edges that help the chain climb onto adjacent sprockets during shifts, and the unidirectional design optimizes the plate geometry for the specific forces generated during front and rear derailleur movements. Campagnolo pairs the chain with their Ultra-Link connector system, which uses a specially designed pin that locks through the outer plates to hold the chain closed after installation with the UT-CN300 chain tool.

The chain ships with one hundred fourteen links, which works for most road bike frame sizes when paired with standard double cranksets and cassettes up to thirty-four teeth. You trim the chain to length during installation by pushing out pins until you reach the correct number of links for your specific drivetrain setup. The hollow pin construction maintains the strength you need to handle shifting under load while removing material from the center of each pin, which drops the total chain weight to two hundred thirty-nine grams....
