Campagnolo Record 11 Speed ChainCampagnolo Record 11 Speed Chain. The engine of the 11-speed drivetrain is the chain. It has been designed to eliminate all friction with the sprockets adjacent to those in operation. A special treatment ensures smoothness. Campagnolo have reduced the width of the chain to 5.5 millimeters with the new spacing and a new material has been envisaged for the outer links. The pins are hollow inside to reduce the weight while maintaining strength. The Ni-PTFE treatment ensures smoothness and long life. The Ultra-Link™ fastening system guarantees strength and operation with the new 11-speed sprockets.C4004456152
