Redshift Sports, the company that brought you the ShockStop Stem, is back with a new product. This time it’s a suspension seatpost to help cut down on body stress from rough terrain without having to install a full rear suspension system. I bet the Paris-Roubaix riders wished they had this one last week.
The ShockStop Seatpost is an adjustable-stiffness suspension seatpost that delivers 35 mm of travel to smooth out your ride whether you are out on some epic gravel adventure or just dealing with potholes on your daily commute. The seatpost features an internal spring which applies force on the seatpost’s four-bar linkage, which in turn suspends both you and the saddle. As you ride, the seatpost allows the bike to move under you as it encounters uneven terrain, which the company claims 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 so you aren’t being bucked all over the place.
The suspension mechanism of the ShockStop Seatpost can be precisely tuned to match your riding style. First, a user-selectable in-line coil spring means a wide range of riders can take full advantage of the shock-absorbing benefits. Then with the right spring in place, the adjustable preload allows fine tuning of the responsiveness without sacrificing any suspension travel.
The company says that the ShockStop Seatpost lets you ride faster and more efficiently by keeping you stable and instead allowing the bike to absorb the rough terrain. This means you spend more time putting power to the pedals and less time bracing for impacts.
And by integrating elements of the suspension into the seatpost itself, the ShockStop achieves a compact and lightweight design that mates well with all styles of bicycle — gravel / CX, e-bike, commuter, city, road, and even mountain.
The ShockStop Seatpost will fit any bike that has a round seatpost 27.2 mm in diameter or greater (the vast majority of bikes). The system takes just a couple minutes and requires only standard bike tools.
Many of the riders on the South American Epic had ShockStop Suspension Stems on their bikes. I am thinking about adding one to mine for Central Asia this summer and might even consider the seatpost as well since much of the ride will be off road.
You can pre-order your ShockStop Seatpost for $139 over on the company’s Kickstarter campaign. Expected delivery is in November.
