Hello, I have a Campagnolo Victory Strada wheelset in excellent condition. However, on the rear wheel, I have noticed that several of the eyelets are separating from the rim. The front does not have this problem. What causes this? When do I need to be concerned about this? I note that I am a larger rider - 6'3", 215 pounds. Just to be safe, I am considering just finding another rim to rebuild the rear.

Any guidance is appreciated.

Thanks!
