1) Will this likely be replaced under warranty?
2) Is this typical for lightweight rims? I really don't want to be going through this every 1-2 years. I am 6'2" 195, not the lightest rider out there, but no clydesdale by any measure.
I am surprised to hear that - they are supposed to be rather resilient wheels. I have been running my Dura-ace wheelset for just under 6000 miles, but I weigh 43 pounds less than you do, and I guess when I hit a small pot hole, it does not cause the same stress that it would if you hit the same thing. Let me know what happens vis-a-vis the warranty, but I would assume the only way you could sustain a warranty replacement would be with evidence that the wheel simply failed without something unusual happening to it. It will be interesting to see what Shimano's attitude towards customer service is.
