This is the Crossfit Jump Rope from Shvoong Sport. This jump rope took a little bit of time for me to put together. It works great and I was able to adjust it to my height. I love the fact that it comes with an extra cord in case something were to happen to the first one. Shvoong Sport also has a lifetime guarantee. This can be found on Amazon . I received this product at a discounted rate in exchange for a honest review.
