I'm not normally a participant in the "don't get a light bike because it's easier to lose 5 lbs" discussions because I like a nice responsive bike but... even at 215 I have zero interest in:
[h=2]the lightest line of production road bikes ever offered.[/h]
Matter of fact my current wheels are pretty heavy at about 1950 grams and I like them because they stand up to a lot of use. My Roubaix is probably in the 17# range and it's frankly not worth going lighter. It just isn't.

Anyway, it's your money and if you want to get "the lightest production frame ever" and then go for it.
