For us, we've just never seen the need for a suspension seat post. My stoker has done 160 mile rides (cross Florida) and 10 plus hour rides (Everest Challnege) without a suspension seat post and in more comfort than on her single.

And frankly, I don't see an inherent reason that a stoker should need a suspension seat post any more than a rider on a single bike.

The position of the stoker over the rear wheel is not materially different than than a rider on a single bike. So that leaves the stoker getting pounded by unseen obstacles which can be addressed by talking and standing.

Coming from a background of riding rigid mountain bikes, your knees and elbows can give you lots of suspension.

While suspension seat posts obviously work for lots of teams, I think sometimes people,gravitate to them to address problems that can be better addressed by the right seat, right fit, conditioning,and communication.

And as for the cost of weight the point isn't whether a Tetra or a Dragonfly is cost effective, the point is you're paying a boat load for any Calfee tandem, mostly to reduce weight. A free way to get the weight reduction is forgo heavy components like a 420 gram seatpost.
I agree. On the other hand I believe there are some that buy a Calfee primarily for reasons other than weight reduction. Some may just want the best and feel or have been told that Calfee is the best. I don't mean to judge that approach but just want to point out that there are other possible motivations.

My stoker (Kay) has never had a suspension seatpost on any of our 5 tandems during our over 42 years (and over a quarter million miles) of tandeming.
In that time tested lots of prototype and experimental stuff for tandems; the only suspension she liked was the (no longer produced) carbon fiber Softride beam.
However if your stoker insists on suspension, then get it!
Keep your stoker smiling!

Please forgive my ignorance, fietsbob, but I put a Thudbuster ST on my CF single bike about a year ago and haven't noticed any disadvantages. There is the weight, of course, but I start most rides with 3 liters of water in a frame bag along with the usual spares and tools, so I'm not on an ultra lightweight machine, anyhow. I think it helps on all riding surfaces, especially washboard gravel roads.

Are you saying it might damage the CF frame? Is the stoker's seat tube on an ultra lightweight tandem simply not robust enough to handle the stress? It seems to me that the post's shock absorption would result in less torque on the seat post. I'm probably wrong. I am looking for a suspension post to replace the old Giant in-line coil spring model on my steel Santana tandem.

I have one on my folding commuter bike. After a couple weeks and about 60 miles, I am pleasantly surprised by its performance. It's a bit... er... "industrial" looking, and without a rider on the bike it looks like you'd be doing push-ups to stay in place. But the saddle levels out when there's a rider on it, and there is no annoying "bounce" as would be expected from an un-damped spring. I attribute the damping to my (m)ass. ;-)
Photos on the "Rinsten" thread.
Next trial: on my road bike.
