i've purchased the Hyperformance Aero Speed rope + some spare parts like those swivel bearings and 2x cords. When I think of it, all the ropes i've had sofar i had to buy new ones because the rubber cord would get way too thin in the middle. i had to replace 4 jump ropes sofar, and every time i have to give about $15 or $20 to get a new one. this way i'll only need to replace the cord, and as for the handle, it's steel + neoprene so i believe it's gonna do well for conditioning
