Hi There, I picked up a Colnago Bititan two years ago from a friend and absolutly love it. This is my first ti bike. I raced steel throughout the 90's and to compare this to my favorite bike back then (pinarello w/ slx tubing) i would say that the frame is just as stiff, but more responsive and very comfy. It rides like my old favorite used to with my tubular race wheels on...i have mavic open 4 clinchers on the bititan. I have heard that the older bititans (round top tube) crack at the bb but that the newer ones with the diamond shaped top tube dont crack...we will see. Hope it holds together i love the ride.
