Cane Creek Thudbuster ST Elastomer for Suspended Seatpost

The Thudbuster ST can be tuned for different riders (weight and riding styles) by selecting the right elastomer. Start with the softest elastomer recommended for the given rider weight. You may want to increase the stiffness by using a harder elastomer. Never use an elastomer softer than recommended for your weight.
