This was the only combination Dropper Suspension and Seat Post that I could find. The reviews indicated that it was a very high-quality unit but since it had both features combined, would not provide as much suspension as other seat suspension systems. The common claim I read was it would take the harshness out of the hardest of bumps. I found the unit very easy to install. The cable and trigger system seemed complicated but were not once you got into it. The dropper system works very well but I found the suspension system much better than expected. It provides noticeable absorption over all bumps and make the ride more comfortable w/o sacrificing road feel and handling. A great unit!
