Bad Luck With Tamer Seatposts
 

This is the second Tamer PivotPlus seatpost that has broken on us.

We do not use suspension seatposts . . .

Stoker is happy with her Specialized CG-R.

Stoker is happy with her Thomson Elite.

My stoker is happy with her Thudbuster

With 130psi in the tires Stoker was happy with brooks sprung saddle the went to 75-80 psi now stoker is happy with unsprung saddle and any seat post.

My stoker was happy with the Tamer until it broke.

I know it's pricey, but we're going to try the Bodyfloat next. However, they're out of stock right now so we'll have to make do with a Thudbuster until we can get one. (Hate the Thudbuster - it bobs constantly.)

I broke two Tamers like yours and gave up on them.

How did yours break? The head came off our first one.

The pin into the plunger broke. My stoker went to a fixed seat post and has ridden it since.

Did your stoker get hurt by that?
Took ours off after picking it up from Santana and put a fixed post on.
Still have the unused post as a paper weight on my desk.

Nor do we...

Not sure I could fit one anyway, but "Bump!" seems to work well enough. Well, most of the time anyway. And if not then it's the captain's fault, of course.

you have to change the elastomer density to a stiffer one ..

perhaps she used the weight that she desires to be, in the elastomer choice .. not the weight she Is. :innocent:

No, the saddle went down on to the fixed part of the post. The first time we were 30 miles from home and my stoker had to ride home with a low saddle. The second time, a few weeks later, the post broke the first day of a week long ride. Fortunately, I brought a fixed seat post with our camping gear and we changed the seat post in camp that evening. The second broken Tamer went into the trash as I was done with them.

Luckily, the seat stayed attached but swung down and back and got stuck in our rear rack. That rear rack saved her - without it, she would have fallen off the back of the saddle onto the rear wheel. I shudder to think how badly she would have been hurt if that had happened.

Very fortunate considering the ugly sharp edges of that Tamer make for a not so tame creature to have between ones legs.

This is just some food for thought, because I know many of you youngsters won't entertain the notion of a Brooks. However, my most comfortable road bike is my 20+ year old Paramount (upgraded to 9 speed Ultegra) which has a Brooks Flyer. Yep, springs and all. On a chip seal road you will really notice that your hands are vibrating but your butt isn't.

Two years back we upgraded from a Burley w/ Softbeam, to our now custom Seven Ti. We're not weight weenies per se but we aren't looking for extra weight. We run Thompson posts and stem with carbon fiber handlebars. She is now fitted well and before long we'll probably get her a custom stem from those Calfee folks. Our wheels for touring (Northern Ireland last year) are Phil 48 holes with Velocity rims. Back close to home we run a set of Spinergy CF spoked rims.

Right now stoker is happy with her Selle Italia Lady Gel on a Thompson Masterpiece, though she had a B68 Brooks on the Burley. All good. However, consider these numbers, just for talking purposes:

Selle Italia Lady - 260 gram, Thudbuster XL - 585 gram, total 845 grams. Thudbuster ST would shave 100 grams.

Brooks Flyer S - 810 gram, Thompson Masterpiece 197 gram, total 1007 grams.

My point is that for +160 grams penalty you can go with a sprung Brooks on a Thompson, rather than a Thudbuster and it won't break. {I shall now duck before the stone throwing begins**

As to the tire pressure thing, we ran 40MM tires with about 70-75 psi on tour. Stoker loved the ride. We run 100 psi with 28mm on the Spinergy rims and she's good with it. I'm really wanting to try a set of Grand Bois tires before long. For those who know of them, we took a big lesson from the Blayley's tandem and ours is very similar, except for canitlever brakes front and back to go with the back disc.

Even if avoiding the broken seat post, If the rider looses grip on the handle bars serious damage can be done to one's anatomy by falling on the spinning rear tire. The top of the tire is moving twice as fast as the bike.

The seat post is the same group as fork, stem, handlebars and crank in the "I do not want it ever to break while riding" department.

Its moving at the same speed as the bike, by definition. The only way you would say "twice" is in relation to the ground. But you're not riding on the ground. You're riding on the bike.

Is is the bottom of the tire stationary from the perspective of the rider? Or, is the front edge of the tire more safe to rub against?

You are correct. It is going twice as fast as the bike in relation to the ground. I was as most people usually due implicitly assuming the stated speed is in relation to the ground. I should have stated it more clearly. If the bike is going 15 mph then the top of the tire is going 30 mph in relation to the ground and 15 mph in relation to you who like the bike are moving 15 mph forward in relation to the ground.

Details aside the point I was attempting to make is that it is potentially more dangerous than falling on something like the top tube.
