Box One Single Speed Chromoly Cogs

Very nice and well made. You can feel the quality just holding it. I am installing this one on another bike build!! More to come!

13T cog. Perfect, looks very stout. I had an ovalized 13T from another manufacturer and it made my chain have tight and loose spots. This one did the trick and was perfect. Quality in a place I needed.

Great Cogs

I have a handful of these in different sizes. They perform as expected and I havent had one fail yet. Put a tiny bit of assembly grease on inner ring for smoother installation and removal.
