I'm tempted to cross-post this to alt.usage.english -- I dithered so over whether to say
"unshipped" "shipped" or "re-shipped". The incident was unshipping, but it was shipping
that got my fingers dirty.

You could carry a pair of latex gloves for those on-the-road repairs.
They take up almost no space, and if you're careful they're reusable dozens of times.

On an international forum, I suspect that my best bet would be to
get wordy and say "I had to put my chain back on the chainwheel".

"Unshipped" would be understood in BrE too, but I'd be more likely to simply say "my chain
came off".

The more unlikely term is "chainwheel". I'd say that's pretty rare in
BrE, foreign-sounding even. It's usually "chainring" for the cogs at the front

Front sprocket to me. Maybe from owning motorcycles.

:-) Motorcycles have sprockets but bicycles have chain rings and cogs :-)
