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.
