Road rider/commuter here. I commute 15 miles one way to work, over chip-seal pavement, concrete, brick, gravel, railroad tracks (with some of the worst pavement transitions I've ever seen) and dirt roads. It is quite the adventure. Orlando's roads are pretty crappy. The sub-base has given in most of the smaller roads from poor construction/maintenance and big trucks driving on roads they shouldn't. The brick around here is TERRIBLE, and a good mile of my commute is pure brick. Not to mention potholes, cracked pavement, and expansion joints in the concrete roads. Needless to say, my nads were taking quite the beating every day. I started to develop bruising in the perennial (not good for male function) and had to stay out of the saddle for a while.

I tried everything. Got fit to my bike, adjust saddle height, ISM Adamo Typhoon seat. It helped, went from 700x25c to 700x32c tires. All this helped, but nothing could stop the punishment. I started standing in the saddle more, but this simply isn't an option over long sections of crap road. It doesn't work, and anyone who tells you stand out of the saddle more has poor form. Most of your work should be done while seated.

Enter the Thudbuster ST. This seatpost ROCKS. I will never go back to a fully rigid bike. I'm young (24 y/o) but I could not take 150 miles of commuting punishment week after week. Now, I stay seated through all but the most punishing of terrain. I weigh 210 lbs and am fairly fit (6'4" rider here) and I use the #7 hard block. It has enough give to take the edge off, but I am considering dropping down to a softer block. When I sit in the saddle it does sag a tad, so adjust your seatpost height accordingly. I cannot feel the actuation of the post while riding, except when I hit the hardest stuff.

I've had my Thudbuster ST since around the time of the product's launch in fall of 2004. Mine spent most of its days on my hardtail, until being moved to the Captain's position of our Cannondale tandem, on which my wife uses a conventional (LT, or "Long Travel") Thudbuster.

I began using the ST after 1½ years on the previous generation long travel Thud. And while the LT offers about 3" of rearward arcing travel sprung and damped through two neoprene elastomers, which are selected & installed to match the rider's weight, the ST travel has been reduced to about 1.3 inches and uses a single large elastomer block.

There are a lot of pro's with Cane Creek's design:

* Both 3G models allow the user to adjust for any pivot slop that develops.

* The head of the post (base of the parallelogram) is machined from the same extrusion as the shaft, not bonded on.

* The saddle rail clamp uses a strong, micro-adjustable two-bolt design.

* The ST (and the LT) offers 15mm of setback. (This, obviously, it only a "pro" if you need it -- but I think this is a benefit to most riders).

I always felt the parallelogram Thudbusters did exactly what they were claimed to. Due to the rearward arcing path the travel follows, the posts respond appropriately to bump forces imparted by the rear wheel. This is in contrast to telescoping type designs where the bump force acts somewhere in the neighborhood of 50°' to the travel of the post. The result is a very low stiction, responsive "seat of the pants" suspension system.

Additionally, the linkage design very effectively combats rotational slop.

Where the ST comes in is taking the edge off sharp impacts, without being nearly as "cush" as its longer-travel sibling.

This isn't a cheap upgrade. But if you can afford it, and have a hardtail (ie, a bike with no rear suspension), it's a worthwhile investment.
The suspension effect is not as 'obvious' as the 'long travel' (LT) version, therefore, if you're after a really 'comfy' ride, go for the long travel.
But note that size limitation applies. For example, at certain rider's height, you can only extend a certain length suitable for yourself. With my height and my bike (a 26" Montague Paratrooper folding bike), only the Short Travel (ST) thudbuster is suitable. However, I have experience the ride of LT version with my 20" bike, and it's a very 'cushy' ride, too much so for my liking, but my wife really appreciates it, as my 20" is a non suspension bike at both ends.
For the ST version, it's effective enough, but definitely won't replace a fully suspended bike. Suitable for riders who does weekend leisure rides, now and then cross country, or even just around town.I would prefer it to be below $100 USD. But given the alternatives, this is a much more elegant and effective solution. Despite the price, I still rate this 4/5 as it is a better solution compare with the alternatives (albeit more expensive). There is a noticeable difference to your ride experience, especially if you take long rides (say about 1 hour or 15 km at a time). BUT, if you're only doing very short rides, and only occasional does so, then I'll wouldn't recommend it. As you probably won't be able to appreciate or feel the effect.
