thanks for replying!
yeah, i would imagine a whole cm would. when i'd referenced leonard zinn's crank arm calculator for leg length, i came up with 175 as ideal for me. all mine are 170 and would be costly to switch. plus, it would mean ditching all my original vintage parts. so, i scrapped the idea in terms of trying to get the saddle down closer to bar height for a good fit on "too small" frames. i say too small, but really the reach on mine are fine. that leg length, though! i just couldn't see 5mm making any difference, either
