I am looking at a 2008 Atomic from a local guy where I live. He claims the bike is in good condition, but I was wondering if there is anything notable I should be looking for as a general problem area? I am also looking at a Demo 7, so anything you just generally need to look at on a DH bike would be appreciated as well: cracks at headtube, squeaky shock, rattling fork, dents here / there ?
