I think it's funny all the anicdotes about the Ghisallo. Especially the guy that says you can bend it with your bare hands. I rode one for years ar 185lbs and still managed to be at the front of all the bunch sprints. My buddy is still riding it since I moved to and Archon T1 which is monumentally stiffer, but I'm not sure is any faster out of the gate. I sure miss the Ghisallo on long bumpy rides though.
In any case I've got a very stiff very light at 13.8lbs (ok it's a little closer to 14 with these whees instead of my 303's)Ti frame I'd match against any CF wonder bike produced today.
