This is one of the reasons I've heard to use a heavier tube as the TT. The logic is the resonance and flex in the "thin" TT that is eliminated by placing a knee against the tube is also eliminated by a "thicker" tube. Bruce Gordon used to talk about this, but seems to have tamed his opinion over time. Has he "mellowed with age", say it isn't so.
I remember many years back talking with someone, I think fitmister Michael Sylvester, about fit and controllability of the bicycle at speed. He talked about the importance of a good front center measurement. As I remember that a too far back front center and the front end wasn't weighed and was likely to shimmy. Too far forward and the rider is "unbalanced" and less able to control the bike. enjoy, Brandon"monkeyman"Ives 99% of comfortable riding is fit in Santa Barbara, Calif.
