Don't let the "8" throw you -- this is a 10-speed chain! Like all of Wippermann's 10-speed chains, the 10S8 has a 5.9mm pin length and 2.2mm roller width. This makes the 10S8 perfectly compatible with all 10-speed drivetrains -- Campagnolo, Shimano, and SRAM. The chain is equipped with a reusable conneX link that allows assembly and disassembly of the chain in seconds, by hand!
