Anyone done a 30 or 31 tooth pulley yet? I called baker, they didn't have anything yet. Andrews website shows a 31 only. I called Zippers who uses Andrews and they told me 30 or 31 but not sure if thats accurate and seemed more interested in selling a chain drive. I need to call Andrews and see if they do have a 30 and if not what their reasoning behind only offering a 31 was.
