For those who have a Tamer Pivot seatpost for the stoker or are thinking about getting one, I am posting some photos showing how to disassemble, reassemble, and adjust the post. We have over 12,000 miles on ours since buying our Santana Niobium in January, 2006 and my stoker loves the post and I have found it easy to maintain. I am well aware that there are many posts in the tandem@hobbes archives and this forum that talk of squeaking. I found that I was putting some drops of lubricant at the top around the piston once a month or so when a squeak would start for the first two years.

However, after I disassembled the post and reassembled it using a grease with some teflon and some heavier oil on the pivot points, I found that it didn't need to be lubricated for the next 3000 miles. One other annoyance in the initial setup is that the chart with the guidelines for how many turns on the adjusting cap for a given weight is for the Mountain post and not the Road post.

I spoke with Tamer by phone to ask about that way back in 2006 when they explained to me that the linkage on the road post has more leverage and needs more turns for a given rider weight than the mountain post (but they do not have a published chart). Once we got it set up by riding several seconds, stopping, taking out the post, increasing tension and repeat (several times), it was great. No movement except for the bumps that needed movement. We count nine exposed threads (refer to the photos)

Anyway, here is the link to Tamer (part of Mountain Racing Products)

and a link to the instructions - a pdf file under their service dept

and finally the photos.

Thanks for posting this. We use and love a Tamer Pivot Plus. We had an aluminum version and it lasted us for four seasons (more than 30,000 K miles). Replaced that post about a year ago and got a very good deal for a carbon one. We did the same calibration procedure that you alluded to. Our only problem has been in the ball/socket interface. After 10K miles or so, the ball starts working its way out of the socket. We rotated the socket 180 degrees and got another 10K miles out of it.

The head came off of our Tamer PivotPlus at 2,500 miles. See https://www.bikeforums.net/tandem-cycling/503532-suspension-seatpost-failure.html

We now have a Thudbuster and although my wife liked the Tamer more, I'm not sure I would ever trust a Tamer post again. I'm not saying that we might not get another one; just that I won't trust it.
