Is there a technique that allows installing a rear wheel into a bike
with a rear derailleur that avoids dropping the chain? As the rear
wheel is inserted, the chain is pulled by the cogs, which causes the
front chain ring to spin backwards and, about half the time, drops the
chain. Replacing the chain then makes a mess. Yeah, I could carry a
glove, but ...

I guess(tm) that it could be solved by securing the chain to the
chainwheel. I wire ties for most everything of the sort:

The local dollar store has these for ummm... $1.00. Secure the chain
to the chainwheel at one point, and see if that helps. If replacing
the rear wheel causes the chainwheel to rotate backwards, then I
guess(tm) securing the chain near the bottom of the chainwheel would
be best. When done, throw away the greasy wire tie.

If it doesn't work, I'll deny ever having suggested it. Not
