Take the ultimate tug behind your boat using the Ronix Core 70 ft Mainline. Grab your favorite board and know you're not going anywhere thanks to the super stiff Dynmeema weave and neoprene core, and adjust the rope to the appropriate length for your sport or riding style by removing any of the three 5 ft take off sections. Don't fuss with other ropes, the Ronix Core 70 ft Mainline wants to be your go-to rope for the coming seasons.
