The NEW ShockStop PRO Endurance Suspension Seatpost is the perfect choice for riders who want a lightweight seatpost with a sporty yet damped feel, highly tunable stiffness, and 35mm of travel. This new design features a combination of elastomers and coil springs for a more progressive spring rate and controlled travel while still maintaining small bump sensitivity and low weight. Perfect for gravel, adventure, road and MTB riders.

More comfort at the saddle means you’ll be able to ride longer, go faster, and maintain control even on the roughest terrain. The optimized four-bar linkage ensures that your saddle angle remains constant through the full range of travel. 

Benefits:

• Sporty Performance - 35mm of damped suspension travel, providing the perfect choice for riders who want lots of suspension travel in a lightweight package and highly tunable stiffness.  
  
• Tunability - This new design features a combination of elastomers and coil springs for a more progressive spring rate and controlled travel while still maintaining small bump sensitivity and low weight. Swappable elastomers and springs allow you to change the suspension stiffness, while a preload adjustment lets you dial in the perfect feel.

What is a Suspension Seatpost?

A suspension seatpost is a specially designed bicycle seatpost featuring shock absorbing construction that helps smooth out bumps in the terrain and reduce the impact to the rider. They are best suited for gravel biking and bikepacking applications but are also used on road bikes to help riders stay in the saddle through rough roads. 

The Shockstop 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. For an ultralight, race-tuned version, choose the ShockStop PRO Suspension Seatpost.

The minimal design of the ShockStop Suspension Seatpost blends seamlessly with the aesthetic of modern gravel, road, and e-bikes. Along with the ShockStop Suspension Stem, this suspension system works together to reduce fatigue and strain, letting you ride farther, faster, and more comfortably.

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 reducing the amount of stress and fatigue on your body, 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, especially on technical terrain.
