I did a search, and browsed through the first several pages, and didn't find what I was looking for, so...

With the onset of colder weather, and the fact that I'm pretty much a weenie about riding in said colder weather, it's about time for me to remount my bike on the trainer and take up residence in front of the TV for riding.

My question is this: are there any (reasonably priced) wireless bike computers that will function reliably on the rear wheel?

Please and thanks.
