The G3 Thudbuster elastomers will fit your seatpost. We have extra-soft ones available on this page. https://canecreek.com/product/thudbuster-st-3g-elastomer/ Part number is BAE0021.
The fit is quite tight. I'd recommend using some soapy water solution to make the surfaces more slippery and use the butt end of a screwdriver (or any firm but not sharp object) to save your fingers and give you a little more pushing force.
To ensure you are using the correct elastomer for your Thudbuster ST, you can review our rider weight chart here: https://canecreek.com/wp-content/uploads/2021/11/Thudbuster_ST_English.pdf
This lists weight ranges and the appropriate elsatomer for your rider weight. The part numbers for each elstomer are listed below the weight chart. You may want to have a few different firmness levels for different riding conditions, terrain, and rider weights.
At 78kg you can use either the Medium which comes installed on the seatpost, or the Soft elastomer which is included along with the seatpost.

Verified OwnerThe Newest Version Thudbuster (4G) Seat Clamp actually holds, IF tightened all the way to the torque limit. The original did not hold. That isn't exactly high praise.

Verified OwnerI got this seatpost after suffering some tailbone soft tissue damage riding my rigid Niner Air 9 Carbon on local gravel trails. I was worried the seatpost would impart a “bouncy” feel especially given my higher weight. I was not only pleasantly surprised that the seatpost stays tight until dampening is needed, I was amazed at the smoothness.
It worked so great I came back home and ordered the eeSilk stem!
