I have no titanium frame experience, but I’m very surprised to hear this, if only because I find a lot of evolution in steel and aluminum frames over the years, as well as changes and improvements in things like carbon forks. I mean, a 2002 Lemond Victoire just looks so different from an ‘18 Lynskey T2, with things like tube diameter and shape, larger headset bearings, and thru-axles being noticeable elements which have had profound impacts on ride quality in other frame materials.
