Handles Only Cable Sold Separately Rx Jump Ropes use an industrial grade multidirectional swivel axis bearing system producing a near frictionless rotation. Our patent pending swivel attachment allows for the cable to reach top speeds or slow it down to suit the athlete’s needs. The Rx philosophy is that it’s not about PURE speed but rather the RIGHT speed to suit each individual athlete’s tempo and timing. The ergonomically contoured handles are 6 inches long and 1 inch in diameter to allow the athlete to maintain the most natural and relaxed grip. This reduces fatigue commonly experienced in the forearms and shoulders. The contoured pinch points allow the athlete to gain pinpoint accuracy to maintain optimal rope shape while still allowing for a relaxed grip. Common in most racquet sports, each handle is hand wrapped with the most absorbent tape grip in the world.
