ActionPost seatpost

Shock absorption and reduction of vibration can have a great impact on reducing strain and uncomfortness on the bike. The ActionPost seatpost reduces these shocks and vibrations massively due to its special elastomer suspension system. This suspension can be adjusted to the rider's weight to make sure the ActionPost seatpost is comfortable for everybody. Ideal for long tour rides.
