The alloy cog is perfect for riders chasing that super lightweight drivetrain, where as the cromo cog offer better resistance to chain wear. Both Cogs are designed to fit Shimano 'HyperGlide' cassette hubs and have a 5mm wide built-in spacer, giving a more solid interface with the cassette body. 16T and above feature cut-outs to save additional weight.
