Earlier quoted context omitted.
Though if your bike isn't expensive or rare and you're in an area with tons of such bikes, secure locking isn't all that important. Just have some sort of lock so it can't be wheeled away inconspicuously. At least that's what everyone here does and it seems to work well enough.
I live in a city where bike theft happens, but you're reasonably sure to come back to an intact bike if the frame is locked to something attached to the ground. The security aspect of the Sheffield stand may not be necessary, but I still prefer them. There are a couple of reasons for that. Spacing is one reason. While you may share a stand with someone else, the next stand is going to be two to three feet away. I don…
Those Sheffield things barely exist here and where they do, they're always taken with other bikes parked all over the place around them so you can't really get your bike back out anyway without lifting other bikes aside. Theres tons of bikes and very little room here since cars need all that's available, so if your bike passes as ordinary, you'll come back to an intact bike regardless of how you lock it, as long as you lock it at all. "Wheelbender" stands haven't caused any wheel issues or other issues for me in three decades of use, and at least those usually are available and have a free spot somewhere, so I wouldn't call them "useless" by a long shot. They may be to you, but I'd rather we over here keep them since the alternative wouldn't be lots and lots of those Sheffield things, there'd be no room for that unless we drastically downsize car parking and I definitely don't see that happen here. I'm sure theft is a huge issue in other places, but it doesn't seem to be that big an issue here so I'm happy if there's any reserved space at all where my bike isn't in someone's way. Just different places having different problems I guess.
