Unless you have a limitless checking account, the Trek Speed Concept 9.9 may only exist on your wish list. Nevertheless, if you've been an extra nice boy or girl this year, and you're able to talk your significant other into buying a top-of-the-line superbike, this one will not disappoint. Equipped with Dura Ace Di2 components, Bontrager Aeolus 5 D3 wheels and Trek's 600 Series OCLV carbon frame, this is a bike that you're guaranteed to set a personal best on. The only question is whether your wallet can handle the aftermath.
