The patent-pending ShockStop Endurance Suspension Seatpost (our original seatpost) provides 35mm of tunable, ultra-responsive suspension travel for the ultimate bump-eating comfort. Ride farther, faster, and more comfortably on the bike you already own, while the ShockStop Endurance Suspension Seatpost lets you float over rough terrain. 

Details
