Hi there! I ride a 49cm Litespeed Tuscany... ti frame... I LOVE this bike... I had a Lemond Buenos Aires prior with a steel frame and while it was a good bike, there really is no comparison IMHO... the ti is more comfortable hands down... when I got it I picked up speed and my climbing improved.. not sure how much of that was mental, but I think it's the bike!!!

I'd recommend test riding both and decide which is more comfortable for YOU! What goes for one does NOT go for all... sigh... that would be wayyyyy too easy! Good luck and hope you're happy on the new ride! And what a nice DH!!!
