Okay, finished my build, and overall for the money, I am impressed. One problem I am having though is a binding in the drivetrain after everything is installed. The belts are not overly tight, not quite loose either, but wouldn't cause this amount of tightness. It seems to be coming from the spur adapter. I used the plastic spur adapter, and put in a 64 pitch spur. I can't remember what brand spur it is, but could it be too thick? I vaguely remember seeing something like this, but I can't find it..... any idea?
