Welcome to the world of 11-speed chains - with the superior shifting properties of the innovative high performance plate geometry.Key Features:Durable, high precision shifting,For all 11-speed drive systems on the market,1/2" x 11/128", pin length: 5.6mm,Weight: 270g/118 links,118 links inc Connex link.Connex 11-speed chains are perfectly suited for the latest generation of shifting systems, which are used in state-of-the-art mountain bikes or road bikes for example. The Connex11sX top model with stainless steel inner links provides maximum wear resistance.Speed Wing, the innovative outer plate, ensures particularly rapid and silent shifting on Connex 11-speed chains. The newly developed peripheral chamfering of the outer plate ensures optimum chain guide and gear-changing performance. And for optimal absorption of the high shear forces through extreme transmission, Connex have implemented a completely innovative process for radial riveting. This process, in combination with a special pin coating, guarantees top performance and long wear.
