I am taking my borranis off one at a time to clean them and grease the spline. I was disappointed to find a serious crack in one of the spokes right where it attaches to the hub. Is this critical, "don't drive the car until it is fixed"? Is there a simple way to get it fixed while the tire is still mounted, or do I have to take the tire off and ship the wheel to a specialist? Any ideas who can fix it for me? I really do not want to have just one wheel totally reconditioned, and I am not ready to pay to have all of the wheels redone. The crack is deep, in fact the connection may just be by a thread.Thanks in advance for some advise.
