Cheers Ken, I know you’ve lived this math on a number of bikes. I noted in a comment above that without increasing fork travel the STA gets steeper (top tube changes), Reach lengthens, etc but where I’m not clear is how much of that reach change is just theoretical.
E.G. welding on a shorter headtube would increase my Reach measurement too (lower stack) but my actual riding position won’t change once I get my bar to the same height relative the saddle.
It’s never mattered to me beyond theory as I’m always overforking bikes and then experimenting with stem length, spacers, bar height and seat position vs. trying to calculate it first.
