If you want a fairly serious tool for road biking I figured I'd throw this out here. Let me say up front I'm not a shill for this company, don't have anything other to do with them besides buying a bike from them.
If you want a full carbon frame/fork/steerer with mid level (sram force or shimano ultegra) components you're looking at $2500-3k. I found this company Stradalli (and another called Rossetti, different owners but similar business idea) on ebay where they sell a lot of bikes.
Full bike, ready to ride sans pedals, all carbon frame and fork, carbon cranks, SRAM force components. $2k, no tax, free shipping. Non-cyclists will choke at that price, you have no idea. Walk into any bike shop and look at specialized, trek, etc... with similar frames an components. It's a deal.
Despite the italian name the frames are pure chinese but then again so are all the major manufacturers. Do a little online research on the cycling forums (roadbikereview) and you'll see few complaints and a lot of good reviews.
Add me to that list. Got mine put together and went on a maiden voyage. Thing is a rocketship, light, stiff, accelerates like crazy. Here is a pic, mine looks exactly like this. If you're in the market just get on ebay and do a search or one on the companies above. Another option is bikesdirect.com, but they've had some spotty customer service issues in the past.
