I riding bud w/ a YZ426 dented his front rim -appx 3" of buldge on lip of rim, maybe 1/2" sticking out at the farthest point. I suspect his tire pressure was low and he did hit a rock at high speed. My question is do the Excel rims have a warranty? Is this fairly common, I thought Excels were the best? He usually runs at 12-13psi, normally fine for the woods stuff, who knows if it was less than that. Any thoughts? Amazingly a bike shop said it was OK, just "go with it" (i quote). Am I crazy or should this be straightend or replaced?
