Did I buy the seatpost for my Scott Sub30. Without the seatpost, it seemed to me at every pothole as if I drove into a wall. For me it was always to the cross. Although I'm not so many kilometers down to about Writing durability but the attenuation I find as opposed to rigid support just great. Of course you can not compare with a full-suspension bike, but what I wanted to achieve with it I have achieved. And I just wanted to catch the extremely hard knocks of asphalt crossings and potholes which they very well makes.
