This Record-level 10-speed chain uses the Ultra Narrow design at 5.9mm width, which accommodates the tighter sprocket spacing required for ten cogs on a standard cassette body. The narrower profile reduces chain noise compared to wider designs because there's less lateral movement when the chain runs at an angle during cross-chaining, and the tighter tolerances mean the derailleur adjustment window becomes more forgiving during setup. Campagnolo achieved this width reduction without compromising strength—lab testing confirmed that traction force, pin retention, and resistance to stretch match the previous wider Record chain.

Hollow pins run through the entire length of the chain, which removes material from the center of each pin while maintaining the structural integrity you need for shifting under load. The lightened outer link plates work with the hollow pins to drop the total chain weight to two hundred fifty-five grams, which represents a twenty-gram reduction compared to the earlier solid-pin Record chain. The nickel-PTFE surface treatment creates a low-friction coating that reduces drag at the roller-to-sprocket contact points and protects the steel from corrosion when moisture gets into the drivetrain.

The chain ships with one hundred fourteen links and includes the HD-Link connector pin for installation. You trim the chain to length by pushing out pins until you reach the correct number of links for your specific crankset and cassette combination, then use the HD-Link with the Campagnolo 10-speed chain tool to close the chain. The connector pin design ensures the chain holds securely at the connection point, and you can identify which link uses the HD-Link by the slightly different pin appearance.... Read More
