A word of warning (with the caveat that it only represents my subjective impressions, not any kind of hard data):

I was in my LBS recently to buy some miscellaneous biking accessories and was seduced to go over and pet the Orbeas, because they are SO sexy. I don't remember WHICH models I was looking at, but both were carbon and in the $4,000/$5,000 range. I lifted up the WSD Orbea, and the "men's" Orbea next to it. Even though the men's bike was a larger size, it was significantly lighter. So make sure you do your homework. They are gorgeous bikes though.
