Rated 5 out of 5 by miducmon It makes what it promises
Very useful to train with roler. I had one without high-regulation, I this one is clearly better. In the older one I put a piece of wood below, this one can be correctly set to any high. The wheel keeps in place during the workout, even if you push hard.
