Suspension Seatposts

My Santana Sovereign originally came with a Tamer telescoping seatpost with elastomers. After a few years my stoker (wife) complained it was not working anymore. So I replaced it with a Rockshox elastomer seatpost. That was over 5 years ago and again she is now saying it doesn't work anymore. I was looking at the Tamer Pivot Plus at A.E. Bike for $107. Has anybody used this and found it be better than telescoping seatposts? Are there any other posts worth considering? I think I used a shim on the Rockshox to adapt it to the Santana 29.8mm seat tube. I can buy a Tamer 29.8mm seatpost but for a lot more money than the 27.2, any reason why I would not want to use the shim and save a bundle of money?

Thanks - Joel

It seems now the new improved version of this seatpost is called the "Trick Dick" although I can not find it by that that name on Tamer's web site.

My wife uses both the telescoping on the triple and the Pivot Plus on the tandem. We both like much better the Pivot plus... it is designed not to actuate unless a threshold force is reached. In other words it helps with bumps but does not make her ride cushy. For me it is a lot easier to set her seat height properly without having her siting on the bike. Besides, all her power goes to the pedals and not up and down.

My wife uses the Pivot Plus, and in it's first season of use, we've found it to be quite functional. As noted above, the nice thing about it is that you can dial in the amount of tension you desire/need, so it will absorb the bumps, but not give you a soft ride. It does squeak quite often, but a little lube in the right places will take care of that for a while.

We use a shim on ours, and haven't had any problems.

Cane Creek Thudbuster. Best Investment I have made on the Tandem on the comfort stakes. I use the 3" version for offroad- but there is a Road use version that is available.

Hi,

Don't forget the Brooks Flyer!!!!! Suspension built into the sadle. I am even willing to discuss this with my wife!!!!!!!!!!!!!!!!!!!

I have a flyer on my touring bike, and am going to put one on the front of our tandem, there is a womanly version available that I am humbly offering to the stoker.

Parallelogram vs telescoping

In MHO, the thudbuster suspension post works better as the functional seat height stays @ the same during movement while the telescoping variety decrease seat height while depressed. i use a 27.2 post with a shim on a 29.8 bike and had a issue with slipping initially now resolved with the addition of tacx carbon assembly paste.

Both telescopic and pivot designs decrease seat height relative to the pedal spindle while depressed. I know the point flightboz is trying to make, however. It is the same one the designers of pivot seatposts make in their ad copy. While setting up the telescopic post that came OEM on our Raleigh Coupe I was able to observe its action intimately, if you know what I mean. I also tried it out myself. I cannot debate the possible superiority of a pivot design but I can say that telescopic designs are certainly useable. The human body is a marvel of adaptation.

I know, you're going with a different brand, just want to put in our vote: the Cane Creek Thudbuster ST (that's the road version). The shim was $7 (the on-line company we used had a simple fitting chart for your seatpost diameter vs shim requirement, if any), fit our '99 Burley Duet easily. Can't believe what a difference it made, like night and day. You gotta get the exact diameter of the seatpost from the original one - it's inscribed there under all that grease. After reading copious on-line reviews and talking with folks at our local tandem shop in Los Altos, the telescoping variety sounded ok, but the parallelogram design made more sense to me. All I know is it works beyond expectation. As has already been said - all of these things work well enough, just avoid the cheap-o's designed for occasional use...

Another vote for the Thudbuster ST.

I've got two different sets of friends who use Tamer Pivot+ and have had the pivots break. The Thudbuster looks to me like it has significantly beefier pivots. A plus is that the Thudbuster has height markings on it. Since I have to raise her seatpost to clamp our tandem in the workstand, I like that.

We've had our Thudbuster for about 6 months. So far the wife's happy so I'm happy.

Years ago, when Thudbuster first hit the market (Cane Creek later acquired it) we tested it.
Quite impressed . . . seems it continues to excel!

The Tamer pivot plus that we own went out for the second time after 10K miles. The pivot rests on a metal disc with a depressed center (indentation) and after aproximately 5K miles the pivot worked its way out of the "indentation". All we do is take out the spring-mechanism counting the number of turns that it takes, rotate the metal disc 90 degrees, regrease (lots of grease), put it back in, and it is good for another 5K miles. When it finally gives up, we will give the cane crek TB a try....if I can not convince my wife to switch to a carbon frame before that.
