Don't let the "8" throw you -- this is a 10-speed chain! This chain has a high grade nickle finish that protects the chain from corrosion and 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 drive trains -- Campagnolo, Shimano, and SRAM.
