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.
Will Hart answered on January 19, 2024 store managerThe 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.
Will Hart answered on January 3, 2024 store managerTo 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.

Wish they still made these in aluminum - black Friday sales made pricing acceptable but carbon is overkill on my 20 year old aluminum frame.
Regardless, these stems and seat posts are great. It's amazing that these and a nice set of 28x700 Continentals make gravel paths and driveways no issue.

This is a quality addition to my gravel bike. I had a dropper post and switched to the eeSilk because I ride some rough trails and gravel roads. I do not notice any bob on the pedal stroke. Highly reccomended!
