The Wolf Tooth Stainless Steel Single Speed Cog utilises extra tall teeth for reliable chain retention when using a chain tensioner. Fitting perfectly onto any Shimano freehub, this cog is optimised for 9, 10 or 11-speed chains but will work with all chains.
Machined in-house at Wolf Tooth's Minnesota HQ from ultra-durable heated treated and electropolished 416 stainless steel, this is a remarkable exercise in top-tier precision engineering. If you're looking for a single speed cog to outlast all others, this is a sure bet.
