Cane Creek Thudbuster Shock-Absorbing Suspension Seatpost 27.2mm, 2 Inches (50mm) Suspension Travel, 3 Elastomer Spring Included, Patented Parallel Linkage Technology Seat Post, Easy Installation
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.
