Welcome to the world of 11-speed chains - with the superior shifting properties of the innovative high performance plate geometry.Durable, high precision shiftingFor all 11-speed drive systems on the market1/2 x 11/128, pin length: 5.6mmWeight: 270g/118 links118 links inc Connex linkConnex 11-speed chains are perfectly suited for the latest generation of shifting systems, which are used in state-of-the-artÊmountain bikesÊorÊroad bikesÊfor example. TheÊConnex11sXÊtop 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.
