Everything looks good, but on the front page things get a little messy. There are simply too many “calls to action”. Twitter, newsletter, facebook, slider with news, apparel, boards, riders. It's simply too many actions crammed into a small space.
Try moving the elements around, or simply adding more whitespace. I would probably just move the social links to the top of the sidebar and call it a day. A small change, but I think you will see a big improvement if you make it.
