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. We have reduced the width of the chain to 5.5 millimetres 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. It is necessary to use tool UT-CN300 to fit it. The Ni-PTFE treatment ensures smoothness and long life. The Ultra-Link fastening system guarantees strength and operation with the new 11-speed sprockets.
