you dropped a lot of weight for a reasonable amount! my wheelset was not disc compatable so i was looking at 2004-2006/7 stuff (needed Brake bosses on the frame).
I saw a Giant nrs carbon at that time sell for 750. but didn't analize the parts group on it. Also didn't contact the seller on weight cause, well, i was looking fora frame.
mine is the small size, 16.5/17?

Good one Brent!
