The XL pulling system yellow!
Indeed, a few of our customers and friends mentioned that when using our first CLASSIC pulley model with stiffer or thicker ropes (10mm and above), sometimes pulling the bottom weight up by securing the sole of the foot on the carabiner felt a little bit too much like hard work. This is why we came up with this new XL model, using double-diameter pulleys. This significantly decreases the friction due to the angle of the rope against the pulley. As for everything else, it works in exactly the same way as the CLASSIC model.
