When I bought my KayakPro Speedstroke in 2011, it came with one spare rope and one spare bungee. It actually uses two of them, one on each side, but it only comes with one. I guess I now know why – after 7 years, I finally need to replace the rope. It was getting a bit ratty looking right where it goes through the front two pulleys, and it was shedding hair all over the place. But today was the last straw, as the bunched up hair started causing it to fall off the front pulleys when I was paddling easy between intervals. It didn’t take too long to replace the rope, as the whole machine is extremely well designed and constructed. And it felt so much better afterwards that I’m thinking I might just buy another rope and replace the other side as well even though it’s not showing the same signs of ratty-ness.
