The MICHE Pistard ORO Track Cog sprocket range are super high performance cogs developed to reduce all unnecessary friction and to maximize smooth functions of components. Hardened steel and finely CNC-machined to eliminate all possible roughness combined together with the innovative WC/C tungsten carbide treatment helps to reduce friction between the components without the need for any lubrication and to achieve maximum durability.
