Seatpost creaking Giant

bikeit65

I have a Giant OCR aluminium road bike which is fitted with a carbon seatpost, and an alloy shim, i continually get a creaking noise coming from the seatpost / shim area of the bike i have tried greasing even tried using different types of grease, plumbers tape hairspray and very thin insulating tape but after a few weeks the noise comes back, so anyone here know any way i can fix this?

Carbon assembly paste?

If it's still there you have a good excuse to buy a new seatpost.

Do away with the shim, get a seatpost to fit directly into the frame

Wrap insulating tape round the shim in an even wrap. Put the shim in the frame and check to see if the post is a tighter sliding fit, add tape as required to get a tight sliding fit. I did this on my Giant and the creak has been absent for one year now.
