I just mounted a Thudbuster St on my Surley LHT build I did this spring. I had a Thudbuster LT on my Dahon folder and that seatpost just floats over everything. I went with the Thudbuster ST on the Surly to just take the edge off busted off roads. I like that I can swap in different elastomers to make it softer or harder riding. I ride with a Brooks B17 and have never been more comfortable on a bike.
