A suspension seatpost is a specially designed bicycle seatpost featuring shock absorbing construction that helps smooth out bumps in the terrain to reduce the impact to the rider. The ShockStop lineup of suspension seatposts feature a proprietary parallelogram design, which allows for the suspension to remain active even when you're seated and pedaling. This means that you can benefit from the suspension's smoothing effect even when you're putting down power, unlike some suspension seatposts that become rigid when you're pedaling. Check out a comparison of our entire lineup of seatposts here. Benefits of a Suspension Seatpost: Improved comfort: Suspension seatposts help to absorb shocks and vibrations from rough roads, reducing stress and fatigue on your body, especially your hands, arms, and back. This can lead to a more comfortable ride and reduced risk of injury. Improved control: By absorbing shock and vibrations, a suspension seatpost can help to maintain traction and stability on rough roads, allowing you to ride with more confidence and control. Reduced fatigue: By allowing you to stay seated & pedaling more often on rough terrain, a suspension seatpost can help you to conserve energy and ride for longer without feeling as tired. Better performance: By allowing you to maintain traction and control on rough roads, a suspension seatpost can help you to ride faster and more efficiently.
