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.

Verified OwnerSo far so good, only wish I discovered Thudbuster 3600 miles ago! An urban cyclist, Seattle’s poorly maintained streets require this “spine-saver!”

[this was written on Jan. 22, '24] I'm a road rider, gravel rider, mtn rider, fatbiker, ... and have been for a number of decades now. This is to say, I am beginning to appreciate any additional comfort based items (not sheepskin seat covers, but truly performance and functionality melded together into great durable products). The Thudbuster LT is one such item (i.e., the G4 version, the latest version). My household has 10 bikes. There are now 6 Cane Creek posts on those bikes:
gravel bikes: 2 x eesilk+ (carbon)
back-up road / light gravel: 1 x eesilk
mtn (hardtail): 1 x Thudbuster LT (G4)
fatbikes: 2 x Thudbuster LT (G4)
The single post I wish had more 'squishy-comfort' would be the road bike's eesilk (so I just ordered a softer rubber bumper). A suggestion for a road rider looking for some additional comfort would be the eesilk+ (gravel) post as it delivers in that category.
The other bikes are now better bikes because of these posts. The more squish, the better (it seems). My fatbikes are the latest to be adorned with such squishy goodness. I did go to softer bumpers than is recommended, that may just be me but I read it's very common. My fatbiking is only done in the winter in Ontario (Canada) when the temperatures are well below freezing (i.e., -10C, approx. 14F). While it's true that running 5 inch tires with 5 psi provides significant 'squish', ... that addition of the Thudbuster LT is everything to make the ride more comfortable and non-punishing (except in your muscles, depending on your effort).
These posts do not look 'stupid', they look great. They are also easy enough to swap in different bumpers is so desired. I'm also running the neoprene overboot for the Thudbuster LTs I'm running. They may or may not be worthwhile but I'm willing to buy and install the overboots to protect my equipment. The overboots also have a big strip of reflective tape on the back and that will certainly keep your friends from losing you in the forest in the dark winter while you're out fatbiking in the late evening.
One suggestion I have though is for sizing. Given the transferability of the post to other bikes I suggest buying the 27.2mm size and using a shim for larger seat-tubes. This allows the post to be swapped out when it's time to sell the 31.6mm seat-tubed fatbike (or what-have-you). The reason for this is to allow you to keep the post and use it on different bikes in your stable. I'm currently running two 27.2mm Thudbuster LT seatposts with shims and both are as 'good / sturdy / noise-free' as the others. Shims are cheap, the LT itself is not.
Cheers.

Definitely 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.
I’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!!)..
Great deal, saved $100 and the product is pretty amazing. So many injuries prevented me from biking, but small adjustments, stem suspension and the Thidbuster makes my rides safe and tolerable. Feel less pain and recovery is better too. Thanks again

I installed the thudbuster on my wife’s city cruiser, she finds it much more comfortable going over the bumps and cracks in the pavement.
Thudbuster LT SP7A272 works great at reducing the “bumps” on the trail or on the road getting to the trail. It was exactly what my Trek Xcaliber 9 Hardtail needed to mitigate the “hard knocks”!
