The Thudbuster G4 is superior to its predecessor in every way. Building on Thudbuster's proven parallel linkage technology we have completely re-designed the seatpost for increased durability and additional suspension travel, as well as ease of use through tool-free elastomer change and a single-bolt seat clamp design. By improving on this already legendary design, we're confident to say that the Thudbuster G4 is the most advanced suspension seatpost ever made.

Key Features: Maximum Comfort: Up to 90mm of travel (movement) for maximum suspension and shock absorption.

Legendary Reputation: The Thudbuster from Cane Creek is known around the world as the most versatile and effective suspension seatpost available.

Tunable: With a range of elastomer spring rates available, the Thudbuster is tunable to match your weight and riding preference.

Force absorbing technology: Parallel Linkage technology stays in the direct path of the natural travel of the rear wheel. 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.
