Um,, i am not quite sure how people can do that to rims.......... I had an echo 06 rim from last november, maybe a little earlier until just under a month ago, and it was fine, they hold grinds very well, i never dented it, it did have a small flatspot, but NOTHING like that pic above and i only got that from a harsh ride in bristol with under 20psi This coming from a rider who is Atlest 6st heavier than most of the people on this forum!!!!! Adam PS; In my oppinion with you being not the smoothest person on the planet Ash, u may want to steer clear, but as i said, i never had any problems with mine.......
