Black Track Cog CrMo

This CNC machined and heat-treated CrMo steel cog will last longer than practically any other drivetrain part. We recommend using with our steel lockring.

Always ensure your chain is both clean and lubricated and always change your chain when it reaches 0.75% wear to ensure other drivetrain parts remain in good shape.
