I cannot agree and feel compelled to reply because I think others
could be misled. I'm no heavyweight (170 lbs.) and commute on a 2-TT
60cm Hillborne. Granted I carry a commuters load in the rear but
nothing close to a 90 lbs. bike. When I stand to climb hills, which I
do every day, I'll get a "bit" of chain rub on the front derailleur
even when the adjustment is finely tuned; friction shifting of
course. I'm no expert, but I believe this would be caused by frame
flex. AND THAT"s with a 2nd top tube. I'd hate to think what this
particular frame would be like .... without. So the ride is not as
stiff as some might believe.
Matt, I think you are wrong. I weigh 50 lb more than you, and when I
climb out of the saddle with my George Longstaff (standard diam 7/5/7
with 8/5/8 downtube, and so vastly more flexible than your Hillborne) I
have no front derailleur chain rub. In fact, I have never had front
derailleur chain rub from riding out of the saddle. If there's a problem
there, I'm quite sure it isn't frame flex that's the cause.
As for the frame's stiffness, I'm quite confident that it is at least as
stiff as a 60 cm Rambouillet or a 60 cm Saluki, both of which I formerly
owned and sold because I felt they were too stiff for me.
