Replaces the Swivel Bearing System on the Aero Speed, Rope Master and Cross Speed Jump Ropes. Use the wrench that came with the original rope to loosen/tighten the swivels.
- The patented swivel bearing system eliminates friction and drag, prevents rope tangle and provides ultra fast and smooth turning action with control in all directions.
- Durability may vary based on personal use and care. It can range from 6 months to a year or even longer.
- Incorrect jumping technique, excessive dropping of handles and jerky arm movements can put additional stress on the swivel bearings and cause premature breakage.
