The latest generation Thudbuster LT is superior to its predecessor in every way. Building on Thudbuster’s proven parallel linkage technology we have completely re-designed the seatpost for increased durability, additional suspension travel, as well as ease of use through tool-free elastomer change and a single-bolt seat clamp design.
By improving on this already legendary design, we’re confident to say that the newest generation Thudbuster is the most advanced suspension seatpost ever made.
The Thudbuster Parallel Linkage technology stays in the direct path of the natural travel of the rear wheel. As a bump lifts the back of a bicycle, the rear wheel pushes up and forward into the rider. The Thudbuster works by compressing along the exact opposite path — down and rearward — absorbing force at the same rate.
This results in a natural suspension feel without being overly active, and allows for more travel without compromising pedaling position.

Many things but primarily the amount of travel (suspension) offered... eeSilk offers 20mm while Thudbuster LT offers 90mm. You can compare the specifications of each seatpost on our website: https://canecreek.com/seatposts-category/
250 lbs max for the Thudbuster LT and elastomer choice is based on rider weight and rider preference. For riders who are closer to the threshold of 250 lbs we recommend running a firmer elastomer.
At 226lbs on the Thudbuster LT you would have the best performance on either the ""X Firm"" or ""Firm"" elastomer. For riding on smoother surfaces you may find the ""X-Firm"" to be prefferable. You can find these on our website and the part numbers are below.
X-Firm Elastomer - AAE0299-81
Firm Elastomer - AAE0299-75

Verified OwnerDefinitely improves impact on small to medium bumps and roots. I’m 170 pounds with my camel pack. The medium elsatomer thing was too harsh so I ordered the softest one with slight improvement. It still produces the boing effect on large bumps like the Suntour post that this replaces. I’m using this on a hard tail trail bike on intermediate trails with lots of roots, so maybe I’m being a little harsh? I’d like to see a coil spring inside the post so it would cover large bumps as well as small and medium roots. That would be awesome. I bought the 27.2 mm post and will try this on my XC bike with adapter where I think it will be most helpful. Worth the money if you ride a lot or have health issues like me.

Verified OwnerI've owned one of the original Thudbusters since 2003 and loved it. This one is to replace a eeSilk+ that just wasn't + enough on the Baja Divide - love the extra travel already.. Solid build with no play (can't say the same about the eeSilk) and a super-easy seat clamp mechanism (finally!!)..
