The Ultra SS is Onyx Racing's own stainless cog, made specifically to fit Onyx OX drivers rather than adapted from a generic cassette cog.
It is broached to the same splines every time for a consistent fit, heat treated stainless steel for durability, and set up for a single speed 3/32 inch chain. Made in the USA, in silver.
