equipped with the seat post and a year ago scarce have since about 1200 Tour kilometers driven. My first impression was positive, the principle conditional spring action of a parallelogram seatpost unlike the telescopic spring! The transient response in the form of a short circular path cutout I personally feel much more pleasant than the rigid, one-dimensional absorb "shocks". At the small additional forward and backward movement, I had gotten used to this very quickly. The individual adjustment of hardness works very simply, amazingly accurate and sustainable. Here, the range moves quite between "litter" and "sporty-taut". The slightly backward offset seat position by the geometry of the seat post was not such a big change that could not have been by the displacement of the seat and / or the re-adjustment of the stem / handlebar can be corrected with me. Changes in the bearing clearance are no signs (I have twice "oiled"). The uniform function was not affected by temperature differences. (Type and weight of the part are quite as so "massively" to denote that the "Carbon / Titan Group" among us even better, the finger leaves them away before they double their weight frame .... Mind you treated this review the interplay the product with a touring bike so .... asphalt with potholes, dirt roads and cobblestones in travel speed under load, without paying attention to every gram! Therefore, an assessment of the seatpost as "Fully-replacement" in hardcore Cross of power Downhill -Friends not be equated without further ado!). In the area of commuting and over long distances with varying Road surface mounting of Suntour for me to now yielded a less tiring and more relaxed cycling than before! In this respect, the investment has definitely paid off at a fair price, even if you can still now not make an truly lasting durability. ,
