With the “IronSpin” jump rope from TOP TEN, you can improve your endurance, speed, and coordination—exactly what matters later in the ring and on the tatami. The ergonomic handles with a non-slip grip zone fit securely in your hand, while the steel cable runs smoothly even at high speeds thanks to ball bearings. The length of the PVC-coated steel cable can be easily adjusted using the one-touch system. Removable 30-gram weight bars in the handle allow you to customize the training resistance of the TOP TEN “IronSpin” speed rope to your individual needs.
