I posted on this subject in 2005. The really loud creak from the seat was causing me grief, and it was getting worse. I was genuinely concerned the seat was going to fail, but could find no cracks in the seat.
However, I recently found out what it was. The skewers that hold the seat in place had oil on them, and the oil had made its way onto the face of the washers on the skewers which press on the seat mounting to hold it in place.
Cleaned everything up, back to silent seat again.
In my experience one uses oil to stop squeaks, but in this case it was causing it.
Any mechanically-minded people out there with an explanation?

Interesting.
I had the same squeak which went away when I put a 1 inch wood spacer between the skewer mount and the seat back (trying to get a more upright seat position). It took awhile for me to realize the squeek was gone cause I'd gotten used to it. Anyway, still love my SMGT.

A rather vague guess, where you add it to stop squeaks it's to make movement between parts /easier/. In this case you don't things moving at all, so making things move more easily could increase movement from effectively zero to a little bit, which gives rise to creaks.
But I'm no engineer...

Probably close, anyway. Visions had a problem with their skewers and it would increase noise everywhere on the seat, including the seat support straps. Of course, the recall on some was because they would actually fail and your seat would leave the bike, which was discomfiting.

Well whatever reason it's stopped now, after over a year. I took the seat off several times but couldn't figure it out. The seat exiting stage right was my worry. A (very) marginal benefit was that peds in Windsor Great Park heard me coming.
