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. The Ni-PTFE treatment ensures smoothness and long life. The Ultra-Link fastening system guarantees strength and operation with the new 11-speed sprockets.
It is necessary to use tool UT-CN300 (code 759001) to fit the chain.
