My earlier seatpost conventional type had since adopted as unfortunately often too fast common: Too much lateral play. I then tried on another wheel times the expensive model of a well-known German manufacturer of: No wobbling, but only very moderate spring action. On the Internet I found a recent test of a journal of suspension seatposts. I trusted the test and ordered me this seatpost. Was somewhat unusual in that it built up quite high on the seat tube, thus needs more space than conventional models. That went with my 57 cm frame (normal older bike with rigid fork) but just like that. Then, the first practical test: No sagging when to sit on, no noticeable movement while driving. Springs do the seatpost actually only when they really should, for example, when driving a marked unevenness. Gullideckel passed: No problem, it teeters only enjoyable, not a hard punch more. The seatpost responds perfectly, the comfort is greatly increased. One can calmly go back with a lot of pressure, my Marathon Plus springs of course there's a little with. However, this seatpost requires some getting used to at first: One wonders if it teeters sudden and astonished that you have noticed a pothole so little. My conclusion: By far the best seat post that I have ever experienced on a wheel. Therefore smooth 5 Stars!
