As a bump lifts the back of a bicycle, the rear wheel pushes up and forward into the rider. The Thudbuster works by compressing along the exact opposite path — down and rearward — absorbing force at the same rate. This results in a natural suspension feel without being overly active, and allows for more travel without compromising pedaling position.

• Shock Absorption Upgrade with Patented Structure for Comfortable Ride: The Thudbuster Parallel Linkage technology follows the natural path of the rear wheel’s travel. As a bump lifts the back of the bike, the rear wheel pushes up and forward into the rider. The Thudbuster compresses along the opposite path — down and rearward — absorbing force at the same rate. This creates a natural suspension feel without being overly active and allows more travel without compromising the pedaling position.
• Stable Fit with No Sway and No Noise: Designed specifically with the rigors of e-bikes and daily commuting in mind, the latest generation Thudbuster ST includes 50mm of travel to significantly diminish shocks and impacts from broken pavement, cobblestones or any other mixed surfaces. The seat post connects seamlessly with both the bike frame tube and the saddle, ensuring a perfect fit with no looseness, wobbling, or metallic noises, providing a quieter and more stable riding experience.
• Precise Weight Support with 3 elastomers for Easy Switching: The product includes three different elastomers(Soft, Medium, Firm), each supporting riders with weights in the following ranges: 100 - 150lb, 150 - 200lb, and 200 - 250lb. Users can easily swap them according to their needs for the most suitable shock absorption experience. If the rider's weight is less than 100lb, or between 250-330lb, you can purchase an elastomer specifically suited for this weight range(Extra Soft or Extra Firm).
• Quick Installation with No Tools Required: The seatpost installation and elastomer replacement are tool-free, with a simple and convenient adjustment process that allows you to easily enjoy a personalized, comfortable ride. The innovative single-bolt seat clamp design simplifies installation and adjustment, reducing the complexity of setup while maintaining a secure and stable connection.
• Works with Many Different Bike Types: This seatpost can be used on road bikes, gravel bikes, e-bikes (electric), commuter bikes, and adventure bikes for maximum comfort and performance.
