I have a 2011 Giant Anthem X 29er 2, and last weekend I noticed what looks to be a small dent about ĺ of the way down the top tube. Itís very small, and pretty much only noticeable in certain light when it hits it just right. Should I get it checked out? I bought the bike new less than a year ago. I have no idea how it got there because there is no paint damage at all. For all I know I may have bought it that way and just now noticed it.
