I guess I wasn't clear. Sorry. Fully understand the wheel base measurement issue. What I meant is that though I target the imaginary line when setting, I never understood why this is technically relevant. The nominal wheel base design is one thing for convention purposes. Yet, tuning wheel position more or less from nominal may be another. Didn't know. Just asked. Richard Cielec Chicago, Illinois

This is how I set them out of habit but, don't understand why. Does technical data say this is the best location? Not being nit picky, merely looking for the rationale behind habits, customs and wives' tales.
Why? When the wheelbase specification of a frameset is given, this is the place the measurement is taken from, a convention based on how a frame designer/builder planned it. If you think its a wives tale, then I can't help any further.
