I'm looking for a cheap Shimano 10sp compatible rear wheel for use on the trainer primarily, but hopefully good enough as a spare race wheel.

Clincher. Aluminum braking surface. Preferably bombproof. Can be heavy. But at the same time, I'm looking for something a little lighter than the Shimano/Open Pro setups I see on Performance, because I don't need a million spokes. I'd love a Shimano hub, but noisier ones would do .

Hope to spend under $200, depending on the wheel. If I can get something similar to my current rear wheel but slightly nicer, then I'll just upgrade and use the current one as a trainer wheel. For reference, I have a 2006 WH-R560 (old Ultegra level), 20 spoke (radial, 2x).

If you want to unload your whole wheelset, I'll consider it. I could use another set of training wheels for the backup bike. Ideally, I just want to get a trainer wheel and then save up for race wheels, but I'm open to other options.
