The CBD sprockets made of aluminium and stainless steel provide a balance of stability and optimal weight. Sprockets up to 28 teeth are made from high-strength stainless steel for reduced wear and tear and improved stability. Sprockets with 34 teeth are made from aluminium for weight reasons and have a special surface finish to reduce wear.
Optimised for use with Shimano internal gear hubs, this CrMo cog is compatible with e101 EPT single-speed chains and ensure a smooth shift when called into action.
