Cane Creek Thudbuster Elastomer

This elastomer is designed exclusively for Cane Creek's third-generation (3G) Thudbuster suspension seatposts. Please verify that your seatpost is a 3G model before purchasing, as it will not fit earlier or later generations.

The #9 rating indicates this is the stiffest elastomer available for the 3G system. It is best suited for heavier riders who need more support to prevent bottoming out, or for cyclists who prefer a firmer, more responsive pedaling platform with less suspension travel.

Replacing the elastomer is a straightforward maintenance task that typically requires only basic hand tools. You will need to remove the pivot pins from the linkage, swap the old elastomer for the new one, and reassemble the linkage.

Yes, the Thudbuster system is designed to be tunable. Many riders combine different elastomer densities to achieve a specific feel, though you should always follow Cane Creek's guidelines for safe combinations to ensure the linkage operates correctly.

Elastomers are wear items that degrade over time due to exposure to the elements and repeated compression. If you notice your seatpost feeling sluggish, bottoming out easily, or if the elastomer shows visible cracking or deformation, it is time for a replacement.
