Know before you buy
The Thudbuster LT uses a parallel linkage system that moves rearward and downward when you hit a bump. This provides 90mm of active suspension travel, which significantly absorbs road vibrations and impacts compared to a standard rigid post.
Yes, the seatpost features tool-free elastomer adjustments. You can swap or tune the internal elastomers to match your specific weight and riding style for a personalized level of firmness.
The Thudbuster LT is rated for a maximum rider weight of 250 lbs. It is important to stay within this limit to ensure the suspension linkage operates correctly and maintains its structural integrity.
The Thudbuster LT is available in 27.2mm, 30.9mm, and 31.6mm diameters. You must check your current seatpost diameter or your bike frame's specifications to ensure a correct fit, as using the wrong size can damage your frame.
The 31.6mm version weighs approximately 750g. While this adds some weight to your bike compared to a standard alloy post, the trade-off is a substantial increase in comfort on rough terrain.
The single-bolt clamp is designed for convenience and ease of use. While it simplifies the installation process, it remains secure once tightened to the recommended torque specifications.
