You can fix a rubber skipping rope to get it swinging smoothly again. Heavy rubber skipping ropes are used by many speed jumpers because the even weight of the rope moves quickly and predictably. When the handles or rubber rope itself are damaged this balance is thrown off, sending the rope off course. Repair an old broken rubber skipping rope to get it working again and avoid the cost of buying a replacement.
Clean the broken ends of a separated rubber skipping rope with acetone and allow them to air dry.
Apply a few drops of silicone rubber adhesive or flexible multipurpose cement to both cleaned ends and press them together. Rest the glued section on a sheet of aluminium foil to keep it from sticking to the surface. Allow the glue to cure completely according to the manufacturer's instruction on the specific adhesive you are using.
Lubricate the bearings, springs or swivel joint in the handle with a light coat of silicone lubricant. Wipe away excess lubricant with a clean paper towel to avoid dripping.
Wrap damaged rubber skipping rope handles with self-adhesive cushioned grip tape to create a more comfortable grip.
Rubber skipping ropes with a line that has worn thin and broken in several places may need to be replaced. Small repairs to one or two sections can be made without effecting the overall balance of the skipping rope. Store skipping rope loosely coiled and laying flat instead of hanging from a hook to extend the life of the rubber.
