Connex 10S8 10 Speed Chain. For strength, smooth shifting, and superb resistance to corrosion on a 10 speed drivetrain, choose the Connex 10S8 10 speed chain. The 10S8 features a high grade nickel coating which provides an exceptional capacity to resist corrosion especially perfect for those whose rides regularly feature challenging conditions. Furthermore, the optimized geometry of the plates enables extremely rapid and virtually silent gear changes on all derailleur systems. The newly developed peripheral chamfering of the outer plate ensures optimum gear changing performance. And to withstand the high forces of cross gearing under load, Connex developed a completely innovative process for radial riveting. This radial riveting of the pins, in combination with a special pin coating, guarantees top performance and long wear, even for narrow width 10 speed chains. Additionally, this chain includes the renowned Connex Link which provides a simple, tool free means to connect or disconnect the chain.
