Forged from solid aircraft grade aluminum, the F-1 Turbo Speed Jump rope is like no other. Our unique brass bushing design allows for extremely smooth rotations and ultra speeds. The longer (6.5") handles make it easier to generate spin. Finished with a light knurling for a firm, secure, and comfortable grip. The cable is 2.5mm steel wire with a premium nylon coating. The cable is easily adjustable to lengths up to 10ft, to accommodate the tallest athletes.
