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


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


• Go further - reducing fatigue from bumps and vibrations
• Ride faster - energy that is normally wasted suspending your body is converted into forward motion
• Take control - customize your suspension feel to float over obstacles and maintain control


• 35mm of active suspension travel
• Infinitely adjustable stiffness via pre-load adjustment and swappable springs
• Adjusting stiffness / pre-load does not reduce travel
• Swappable springs included to accommodate varied rider weight and preference
• Optimized linkage geometry provides ultra-responsive suspension feel

• Check technical specifications for compatibility

What's in the Box:

• 1 x ShockStop Seatpost
• 2 x springs (1 pre-installed, 1 included in box for increased stiffness)

Different bikes sometimes have different seatpost diameters. The ShockStop Seatpost is 27.2mm in diameter, so if your bike's seatpost is larger, you'll need a shim to adapt our seatpost to your bike's frame. Don't worry though, the shims are super-lightweight and essentially invisible once installed.

Not sure what size seatpost you have currently? There are a couple different ways to find out.

• Most seatposts have the diameter printed somewhere near the bottom of the post. You'll need to remove the seatpost from the bike frame (mark your existing seatpost height with a bit of tape before you remove it so you can replace it easily), and look for a number like 27.2, 30.9, or 31.6 (etc.). That is the diameter of the post.
• If you know the make, model, and year of your bike, you may be able to look up the seatpost diameter online. Feel free to shoot us an email at - we'll see if we can help out.
• Ask your local bike shop - they'll be able to accurately measure your bike's seatpost.

Non-compatible posts: Unfortunately, if your bike's seatpost is smaller than 27.2mm (for example, the 25.4mm posts found on some recent model Cannondale Synapses) our seatpost is currently not compatible with your bike. Likewise, if you have a bike with an aero/oval/non-round seatpost, or if your bike has an integrated seatmast, the seatpost is also not compatible.
