I tried some ideas and unfortunately I still couldn't get my 44 tooth sprocket aligned. So I decided to go ahead and get the CNC 36 or 44 tooth one. But apparently they fit three different sized hubs. Since it's going on a 21 speed Trek mountain bike, what adapter size should I get(1.0 inch for freewheel hubs, 1.5 inch - Most Coaster Brake Hubs (CB-110 and HiStop), or the 1.8 inch adapter). Which size do mountain bikes use? It's an older bike more than 10 years old so I dont know what one to get. Was going to get the one off GASBIKE.NET. My hub is a bigger diameter on one side than the other if that helps Here's a pic...

If you don't hop up the motor the spoke clamp will work
But it is hard to align
Don't know what to say about the tapered hub.
The hub type clamp is made for straight hubs
