The initial spring comfort effect is enormous, the enthusiasm lay down but with time, when I realized that the seatpost knarscht in bumps by hurling back and even good springs when it is fully seated on the saddle. However, if you drive only on level surfaces and maybe on gravel paths and no racing or stooping standing posture is occupying the seat post worth the money (for normal driving) So I give still 4 out of 5 stars.
