Subject: [CR]Re: Vintage Bikes, Vintage Skis, why the difference?

I'm not going to get caught up in this old argument, just suffice it to say that I keep reading about pro's that do not use CF bars, seatposts, etc. I also read a snippet in Velo News last spring, after a rash of crashes in the spring classics, in which Johan Musseuw was pointing the finger at carbon fiber wheels as being too stiff to safely handle the cobbles. And at 200 pounds, and riding poor quality roads on mountain passes, there is no way I would ride any 15 pound bike, no matter what vintage or material. And finally, if modern bikes are so clearly superior in every way, why does Peter Post's record for average speed still stand for Paris-Roubiax?
