This frame is also known as the Ti.Classic. There's a few posts about this frame but from what I remember this frame wasn't even close to the Pro Tour 630 in terms of feel.
I don't know if it is the same one as the Ti.Classic. I have a Ti.Classic from the states, and it plays nice. It says it is an L6. Here in canada they have the Ti.ProTour, but it labeled as an L5. So i wonder where the one level went.
IIRC the Ti.Classic is the same as the Ti.Pro Tour but just different colors with the Classic being red and the Pro Tour being blue. The Ti.Classic was also marketed in the US while the Ti.Pro Tour was marketed in Europe.
