This is the crossfit jump rope from roxow. This is another self assembly jump rope. My boyfriend tried this one out and he loves it. It was just the jump rope he had been searching for. He's planning on using it a lot and is glad that encase it breaks he has an extra cord for back up. Or if you have two people of different heights who want to use it both cords can be cut to height then the handle can be placed on whichever cord is right for their height. This can be found on Amazon . I received this product at a discounted rate in exchange for a honest review.
