Neat feat of engineering, but pointless IMHO. 45K....yeah. That is alot of carbon though and I can appreciate the science/engineering that it took to make all of those parts.

My road bike is about 18 as well but I'm sure I could drop a lot of weight by changing the wheels. I'm starting to realize the stock ones are heavy @ss b*itches!
I have pretty good wheels. Mavic Krysrium's. Dropping weight in mine would be going Dura ace instead of Ultegra, and carbon stem/bars. The frame is mostly aluminum with CF fork and seat stays.
