Amazing.

I looked everywhere, and I found no other suppliers. If you really need them to be double hubbed… there are a few things you can do. And yes, they all involve making it yourself, as its cheaper than getting it custom ordered.

What I would do is buy the hubless sprocket, bore it out, machine a double sided hub, and weld it into the middle of the sprocket. Since everything is steel, its bound to be a very clean and strong weld. The other option (which I’m guessing Dr. Joe would like) is to EDM or CNC the sprocket. First get yourself the sprocket blank (basically the disc of the sprocket with no teeth, and the two hubs, all easy to machine) and then give it to a shop (if you don’t have a CNC) to cut the tooth pattern for you. I’ve cut sprockets on a CNC before, it is pretty easy once you get it programmed. And the sprocket quality is perfect, just like it were bought.

Hope that helps, even though I couldn’t find any suppliers.
