The 5.5 millimetre thickness has been combined with new materials and a special anti-friction treatment which permits outstanding fluidity.
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-Linkâ„¢ fastening system guarantees strength and operation with the 11-speed sprockets.
