I am 6'4" 265 and ride a 62cm Serotta CSi and doesn't flex hardly at all. Ti at this large of a frame is a little wippy, more so in non-custom stock frames. I tested a Seven Ti and it was stiff but a bit springy, especially when I really got down on it and hammered - although, felt pretty interesting. I haven't tried a Legend Ti. Dave, I have always wondered how a Terraplane would feel at this big of a frame.
