Today, I noticed a really small dent in th frame of my Norco CRD2. It is a 7005 Aluminum. I never crashed it, and don't know how the dent came to be, I am guessing from the LBS moving it around. But it is about the diameter of 2 brake cables put together, and say 2mm deep? its round. I did a search and seems like when aluminum dents it pretty much garbage, I just got the bike less than 1 month ago. Should I be worried? Its like a ding, and at some angles I can't even see it.
