Hi Tom and Spectrum-philes,
I'm looking into getting a custom bike, and I was reading some of the archives of the old serotta "phorum" about Ti. From what I read it seems there is a "limit" to how torsionally stiff and snappy you can make a Ti bike before it starts to lose its weight advantages to steel; ie, for "bigger" riders, to get the same torsional stiffness and responsiveness from ti you'd end up with a frame heavier than the equivalent steel frame.
So, my question is, is there a rough line to be drawn in rider weight and riding style where it makes less and less sense to go with ti, disregarding its corrosion and fatigue advantages? At what point do you start recommending a steel frame to someone looking for a torsionally stiff, snappy, responsive racing frame because the Ti frame either can't be made or can only be comparably heavy or heavier than a steel frame?
I'm 165 lbs and like to climb and sprint and bomb down mountain roads, btw...
Thanks, MadRocketSci
