I still believe I hit a pothole on tar. That's my story and I'm sticking to it. Whatever, I've learnt my lesson: I'm now OCD about the pressure. And I agree with Monsieur Cap that the wheels are more vulnerable than the old ones, by design.
Anyway, noticed a familiar picture in May 2014 Offroad & Adventure Mag of a rim with worse symptoms.
Nox, I think my bike is the best compromise for ME. Someone else might like more road, others more offroad orientated bikes. This is my opinion, garnered from knowledge gained mostly here and riding a couple of bikes.
