Ok, I saw that you mentioned in the original post
polymorphself however, I thought that the front wheel was 36 spokes and the rear was 40. Was this a 40 hole hub onto a 36 hole rim? It hardly matters though since the spokes are long regardless of the pattern.
If filing or grinding is the accepted solution for a pro wheel builder (I wouldn't think so), it still should have been done before handing them to you.
Well, give them a chance to get it right.
Oh yea, you have the Schwinn Voyager SP. That came with a 40 spoke rear wheel Did the rim need replacement? Could you not find a 40 hole rim? Is this a quick fix until you find a 40 hole rim? I know rims are in short supply right now.
