Hi Jenny,
Thanks for your feedback. You purchased the Elite cable (suitable for those linking 50-60+ double unders unbroken) on the EVO FRE Speed Rope. The Elite cable will feel heavier than your old rope if you've been using a cheap, lightweight speed cable. The additional cable weight is added to teach cable control and slow the user down, as lightweight speed cables teach one speed (fast). When switched back to a cable that is better suited to their abilities, it can feel heavy. There will be a period of adjustment when changing over to a new rope, especially if your technique is conditioned to using a lightweight cable that you can't feel. The Elite cable will help teach cable control and timing, and help unlearn the bad habits that learning double unders with a lightweight cable teaches. I have full confidence that you'll love the rope once you adjust to the cable weight.
Two tips which we recommend to anyone changing from a lightweight cable to the progressive cable weight system: jump higher and slow the rotation down. The lightweight cable you've been using requires a speedy rotation and a small jump for timing to be accurate. By jumping higher and slowing the rotation down, it gives more time for the cable to pass under your feet twice. Add the small amount of weight in the cable and you're able to control the turn, rather than just keeping up with a fast rope. These tips work for everyone from beginners to CrossFit Games athletes. It's very common for the rope to feel different a) because the handles are so smooth, and b) because the cable weight is different. We have more tips on our social media and YouTube channel.
Our one-time exchange policy allows for the cable to be exchanged. If the cable has been used in the gym there will likely be marks on the cable which we cannot accept an exchange for (used product). If there are no marks on the cable, you're welcome to exchange the cable. I'd recommend staying with the cable you have as long term it will be better for your double under development.
