The Works Z now is finished with electro-less nickel plating which gives the sprocket more of a brushed/natural stainless appearance but does not compromise in performance, durability, corrosion resistance, etc. Unique, exclusive off set tooth design for exceptional self cleaning capabilities, extending the life of the entire chain drive system by removing mud and dirt more efficiently. Perfect for using in adverse off road conditions where extremely wet, muddy and/or sandy conditions are encountered.
