When it comes to jump ropes, longevity seems to drop the more you pay. I’ve worn out a lot of expensive ball-bearing-handled leather ropes before I realized how sturdy and durable the plastic-beaded ones are.
And when the beads in the middle start to get too worn out, just move them to the ends and let the others take their place.
I can’t imagine that plastic tube hitting the sidewalk very long before it has to be replaced.
