Here's a carbon bike that I would mount up with 28c tires and ride dirt roads in a heartbeat. $350! If the picture is accurate, no way is this a 55cm...looks like a 48cm or smaller. Too small for me otherwise I'd go buy it this weekend at $350.
This kind of stuff is why I can't currently bring myself to drop Ducati motorcycle money on a custom bicycle again. Don't get me wrong, I love my Moots MTB...its like a piece of jewelry.
