Technical comment, my Thompson seat posts are noisy. The saddle clamp/carriage bolts creak like crazy, and I'm going to lube up my second post today -- the one on my commuter. With aluminum tubes, the creaking reverberates and sounds like the bike is falling apart.


I hesitate to say this, but on some non-moving metal to metal joints
(not just bicycle parts) I've had success by scraping some paraffin wax
onto the surfaces. It can last a long time. (Let the mockery begin!)


I'm not anti-wax. That would work, but I'll use grease. I was thinking of using PTFEE plumbers paste or anti-seize. I looked at the Thompson site, and it said "Grease only bolt threads. Do not grease under bolt head
or washer and do not use anti-seize." I wonder why no anti-seize.

I never understood that warning/recommendation from Thomson. I have several Thomson posts and always greased every metal to metal contact despite it is a tedious and messy job with Thomson posts. Worst post to change a saddle.

I have a Thomson seat post on one bike that probably was 2nd hand when
I bought it. I just greased it and shoved it in the seat tube and
tightened up the clamp bolt. It's been there for probably 3 years
without moving :-)
