Sharing a bicycle sounds straightforward until the handoff involves changing the fit. The useful decision is not simply whether two people can use the same bike, but whether the adjustments between rides are easy to repeat without turning each outing into setup work. Fit range and adjustment boundaries belong in that decision, but I would not treat a comfortable setting for one rider as automatically right for another.
For anyone weighing one shared bike against separate setups, what makes the adjustments manageable enough that you would keep sharing rather than choose another setup? I would put the routine itself at the center: if it takes too much coordination to get the bike ready for each person, convenience may not be much of a benefit.
I’d share only if the fit differences are mostly saddle height. Mark the seatpost and keep each rider’s saddle height written down, then the handoff is quick and repeatable. If you’re also moving the saddle fore-aft or changing the cockpit to get the other rider comfortable, that’s no longer a simple adjustment, and I’d rather have separate setups than pretend one position suits both.
I wouldn’t make a fore-aft adjustment an automatic deal-breaker. If the saddle’s rail position is marked and the clamp returns it reliably, that’s one more repeatable step, not a reason by itself to buy another bike. But if every handoff means changing height, setback, tilt and cockpit, the setup ritual can eat the convenience pretty quickly. Saddle height alone is a sensible limit for some people, not a universal one.

I’d tolerate height and marked fore-aft, but not repeated cockpit changes. If one rider needs the bars moved to get comfortable, I’d rather have a second bike than make that part of every handoff.
That’s about where I’d draw it too, with one distinction: moving the bars or stem is a real fit change; adjusting lever reach, where the shifter allows it, can be a quick handoff setting. Different hand sizes don’t automatically mean the bars need moving, but if the second rider needs a different bar position to get comfortable, I’d stop calling it an easy shared setup.
Where the levers allow it, I’d try reach adjustment for a hand-size difference before moving the bars, provided both riders can brake confidently from the hoods. It brings the lever blade closer; it doesn’t bring the hoods closer, so it won’t fix bars that are too far away.

I’d check both reach settings from the drops too. The closer setting can leave too little blade-to-bar clearance under a firm pull, which makes it a poor handoff setting even if it feels fine on the hoods.
