inseam is important eventually, but
1. most people think of this as "pants size." without getting them to make the effort to accurately measure "cycling inseam," it could be misleading. to avoid confusion, I would ask this question LAST
2. it's down the list in order of importance, even when measured correctly.
3. with the sloping top tube on many bikes, the standover varies depending on where you stand over the bike. standover is not a
fit measurement, but it's a safety concern for people on extreme ends of the height spectrum.
4. if the request for inseam has anything to do with determining the rider's proportions—like if they have long legs for their height—that could be interesting. however, it's a factor that most keyboard bike fitters (myself included) can't use effectively. the rider in question has to get on the bike IRL for that to be useful in the end. unless someone has mutant-like long/short legs, 99% of bikes in a size designed to fit someone of their height will fit regardless of standover.
