This is a Minoura 3-roller trainer. I purchased and used it several years ago. There are no major scratches or damage, and I think it can be used without any problems in the future. The specifications are copied and pasted from the HP. Please take a look at them as a reference, as there may be minor differences depending on the year of manufacture.
