The context for the question I suppose is that I’m sort of perpetually thinking about my next frame. For practical reasons I keep two bikes. I’m feeling like I’m about ready for another one, and want to go with a 23” or 24” frame, and vintage. So I know that I really enjoy how the 73 squared bike rides and handles, and don’t really care so far for the way the 72/71 bike rides/handles. I’ve had it for 6 or 7 years, longer than anything else that’s come and gone during that time, but didn’t start measuring anything until the last 3 frames. So when I replace it, ideally I can avoid a geometry that provides similar handling characteristics by understanding a little about what makes a frame with a given geometry handle in a very general sense. I don’t have enough experience as a rider to say “this one planes” or “stiff yet compliant”. I don’t know why I suspect the differences I’m experiencing are geometry related. In my mind that seemed like the logical place to look, but I admit I didn’t explore the logic much. I suppose if the differences in handling come from too many variables to ever produce any consistent result then I might be wasting my time, but I find bike stuff to be a very satisfying way to waste time.
