I know I'll get a new quick release skewer, something cheap and heavy, for use when I'm on the trainer.

But I've heard some people say to get seperate wheels for using the trainer. Is it really a problem to use your good road wheels on the trainer?

Should I just get the qr skewer and use old tires and my regular wheels? (much cheaper than spare wheels)

I'm planning to get the 1UpUSA trainer if that makes a difference.
