My experience with zero pros is not good. A couple years ago I bought an EZ-Ryde rear suspension that came with zero pros. The first ride on it, I couldn't believe the difference!! It was plush but also took the big bumps very well. The very next ride, without changing anything, the ride SUCKED!! It felt completely different than what I had experienced on the first ride. Then I remembered that my stock suspension (that also had zero pro shocks) had gotten worse, and that a few years ago I had them all rebuilt because of that, and the same thing, one ride later and they felt like crap again. ONE RIDE!! I now have zbroz and after getting them dialed in for my riding, I love them!! They are consistant and work very well, and most importantly after many rides, they still feel good.
