How can a seat post be so noisy? I dunno but I have to take it out and wipe it clean practically all the time. Its a carbon fibre seat post that inserts into a metal spacer which inserts into the seat tube. I regularly clean all of these inside and out as good as I can. Its just that after a short while the dam thing starts creaking very badly again. Any suggestions for a long term fix? I just take a hex wrench and some wet wipes which is less than ideal.
