SILENCE, ACTION. THE NEW CHORUS™ 11-SPEED CHAIN IS QUIETER THAN EVER.
The new 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-Link™ fastening system guarantees strength and operation with the new 11-speed sprockets.
width 5,5 mm - Ni-PTFE Finish - 114 links - requires Ultra-Link™ for 11s chain - 11s outer link - new material for outer link.
