The Momentum Carbon Fiber Speed rope is the lightest jump rope available on the market. It’s not recommended for beginners or for the faint of heart. This jump rope is fast, smooth, and ultra light. When doing long sets of DU’s you muscle stamina will last with little to burn you out. This rope has the same guts as our Elite line for a fast, smooth spinning feel and a light, infinitely adjustable PVC coated cable.
