I developed a wobble in my rear wheel a few days ago. Since there was no broken spoke and I didn't have time to true it up right away I just opened the brakes up and rode it with the wobble. On the way home yesterday I decided to stop by the LBS and get my favorite wrench to true it up since I knew it would be a few days before I got time. Within minutes he came out into the shop to tell me he couldn't help me then showed me where the nipple had pulled through the rim! It hadn't simple popped through; an area of the rim about 2 cm in diameter was bulged with cracks radiating from the spoke hole. The wheel was true and, as far as I could tell, consistently tensioned. The mechanic plucked several spokes and said they certainly didn't seem over-tightened to him.
Has anyone ever experienced this? Is there any chance of getting a new rim from Mavic? This is a 36-hole Mavic MA3, drive side spoke. I wouldn't really expect Mavic to replace it since there are so many bad things that can be done to a wheel. On the other hand, if there is a possibility I am not above asking.
