KMC S1 Rustbuster Chain Description: The KMC S1 Rustbuster Chain is a single-speed chain that is designed to last longer in harsh conditions such as a beachfront with the sand and salt, or for a winter commuter bike to hold up to salt and other road treatments. The innovative "Rustbuster" finish prevents corrosion and rust from the surface of the chain, and when this finish is combined with regular cleaning and lubrication, the treatment will help to lengthen the life of the chain and help the chain to operate quietly. This chain has enough length to fit onto beach cruisers and other big wheel bikes, and is compatible with internally geared drivetrains and single speed bicycles.
