WANTED: suspension seatpost REWARD: $$$

[Pavement01]

Looking for a suspension seatpost like a Suntour SP25 NCX or Thudbuster LT etc. 

Budget is a few thousand depending on what's available. 

FYI the local suppliers are out of stock of the Suntour that's why I'm now looking for someone that wants to sell theirs. 

Seatpost is 31.6mm but I wouldn't be opposed to using a shim if yours is smaller in diameter. 350mm or longer is required.

Having tried a few different types (I have back issues) I can really, strongly, and only, recommend a Thudbuster. Thirteen Industries and Protunebike are agents. Thudbusters are just another level compared to the others, the beauty being you don’t even know or remember they’re there until you sit on a rigid seatpost again and get the shock of your life 😂 Of course any suspension seatpost adds weight but the Thudbuster is a piece of genius.

Meant Thirteen Industries not eThirteen

PS would recommend purchasing a new, current generation one. Elastomers for older models are not readily available from Cane Creek themselves and you may end up in a new old stock situation which is not ideal for elastomers. They do perish.

Hey @RobynE 🚵‍♀️

Have you ever tried the Thudbuster LT? It looks like a solid option. I’m mainly after something that’ll take the sting out of long singletrack or jeep track rides.

Those washboard corrugations on gravel absolutely destroy the lower back on a hardtail — and once you’re 70km in, your legs just don’t have the same spring to lift off the saddle anymore.

I was actually set on getting the new Suntour post, but it seems everyone’s out of stock at the moment. The Thudbuster LT is a bit of a stretch price-wise, so it’ll mean another month or two of saving… but if it’s really that good, I might just go for it.

That’s what I have now, the previous generation, but I’ve struggled to get a replacement elastomer (bought it second hand three years ago) so I’ve made eyes at the SO for a new one for my birthday next month 😂 

The difference in chatter, corrugation and even large bumps is unbelievable. And it doesn’t squeak or rock front to back or side to side. 

Because I have not been able to get the elastomer and the old elastomer completely collapsed, I bought a Zoom coil seatpost off Temu for like R300, and it’s doing the job in the meantime. Nowhere near the quality of the Thudbuster, not by miles, but better than any rigid seatpost. It does have a bit of a clunk in the spring but it’s still better than “naked” hardtail.

Thudbuster ST is in stock. Your LBS should be able to order, otherwise DM me and I'll organise for you.

If you'd prefer the LT I can check when more are coming in.

Morning, I can supply you with a Cane Creek as we distribute from Pretoria.

Send us a PM if interested

Throwing the Redshift ShockStop seatpost into the mix, an elegant option for a few dollars more...I cannot compare it to others mentioned here but to solid seatposts, this is the cheese to the chalk!!!!

They have stem suspensions that I can also attest to! Go check them out!

Thanks for the tips. I managed to find a BySchulz g.2 seatpost for 2.5k imported (60% off sale) from merlincycles.

There is a company in CT, will try find the name, that make custom poly bushings and elastomers. They might be able to make a mold and new ones for you. They made cush dampers for my F800GS motorbike from poly, can also provide different density.
