A vintage set of training rollers for cycling training. I've had these since the early 1980s and have only used them a few times. I was told these were sold under the Cinelli brand but there isn't anything stamped or printed on them. That said, they feel very smooth with solid heavy duty construction. I haven't lived anywhere where I could use them since the first three years I had them, so basically they haven't been used in decades but have always been stored indoors. They have a brand new belt just installed. They could be cleaned up a bit as they've been hanging from the ceiling in my garage for years and have some dust and grime, but nothing that would affect their function. Why haven't I used them? Because they must be set up on a perfectly level surface and I haven't lived anywhere with a good place to ride on them. Hard to believe, but true. Note that unlike some newer rollers, these do not fold up. Otherwise, they work as well as they ever have and are heavy enough to provide real stability. I'm generally available to show them but as mentioned I don't have a good safe place to try them out. Thanks, Bob
