I had to ride a ways on a flat. Now when I went to change, I noticed a crack from edge to 1/2 way to center(in between spokes)on alum rim. Looks like where factore seam/weld is. Any problem in having this welded up & holding successfully. I dont care about the site of the bead of weld.(I would not grind down for apperarce) Has anyone else done this?
