After I've been thinking for a while, my bike, with which I am otherwise very satisfied in against a full-suspension bike, I was advised of spring seatposts. After I have wavered between the almost 3x more expensive Cane Creek and support this, me the good reviews have led to the low-cost solution. On the part of the quality of workmanship you do not have to accept the slightest restriction, despite the low price. The seatpost makes a very high-quality impression. Nothing game, nothing wobbles - not even after numerous kilometers. Of course I can not judge whether the Cane Creek seatpost would not have been better. Nevertheless, I regret my decision in any case. For many trips away I have come to appreciate the Sun Tour Prop. Despite its low height it bounces easily even small bumps on the road, such as stones or smaller potholes, easily away. Off-road, the seat post represents a considerable improvement and, although I exceed the recommended 100 kilo limit, it is extremely rare that the spring support compresses until it stops. Due to its low height, it is also easily combined with most bikes, which you can not tell from the Cane Creek seatpost. Here I would probably get into trouble because it builds more than twice as high.
Given the price, this suspension seatpost is an excellent solution for every cross-country non-MTB'ler.
