This is a rim-drive Minoura bike trainer in excellent physical and operational condition. There is no need to swap bike tires since it drives the rim of the bike; it takes about 30 seconds to attach or remove your normal bike to the trainer. $75. I still have the instruction manual that I'll give along with the trainer.

Here's a link to an identical item, except that mine is black (this link is not my auction, I'm just listing it for price comparison)
