I bought a full CF cyclocross bike a few months back off craigslist. I was told it was a custom order for Javelin when they sponsored a cycling team. I was pretty busy with school when I bought it, but the deal was too good to pass up. I've tried to find other frames with similar designs, but haven't seen anything like it so far. In particular, the CF tubes look lugged, but they are in fact flush with each other. And the tubes are in different, non-uniform shapes (top tube is near triangular, downtube starts off near triangular, but ends up round). Since it's a custom bike, I'm not sure much could be said about. The seller said Javelin carbon frames are made by Antonio Sarto, though I have no way of verifying any of this. I figure there might be experts here that can add their 2 cents about it.
It's currently set up as a road bike with some cheap parts I had lying around. Money is tight since I'm heading back to school, so this will have to do for the next few years.
