Redshift has created the ShockStop ($139 & Up) suspension seat! The ShockStop is an adjustable-stiffness suspension seatpost that will dramatically improve your ride by smoothing out the road. It is equally suited for an epic gravel adventure or just dealing with potholes on your daily commute. You can even adjust the spring rate and pre-load to match your specific riding style.
The ShockStop Seatpost suspends your body, isolating you from the imperfections of the road and trail. We optimized the travel and suspension kinematics to provide a plush, bottomless feel.
The ShockStop has an internal spring which applies force on the seatpost's four-bar linkage, which in turn suspends the saddle and rider. As you ride, the seatpost allows the bike to move under you as it encounters uneven terrain, which reduces the accumulated effects of bumps and vibrations by up to 60%. The four-bar linkage ensures that your saddle angle remains constant through the full travel of the suspension.
The ShockStop Seatpost will fit any bike that has a round seatpost 27.2mm in diameter or greater (the vast majority of bikes). If your bike has a seatpost that is larger than 27.2mm in diameter, inexpensive shims can be used to make it fit perfectly.
