This is a MINOURA FG540 hybrid roller, which is foldable. I used it about 5 or 6 years ago, but I'm selling it now because I don't use it anymore. I checked its operation just in case, and it works without any problems! You can train indoors, so you don't have to worry about the weather. *Please refrain from purchasing if you are nervous about used items. *There is no box, so it will be shipped in recycled cardboard.
