Creaking seatpost on Giant TCR(5 posts)

Creaking seatpost on Giant TCRHelp!
Feb 5, 2002 9:08 PM
My Giant TCR is making a very annoying creaking sound. I've finally found the source, and it's coming from the seatpost. How can I fix this? I started to grease it, but it's that aero/carbon style post, and I wasn't sure if that was a safe thing to do or not. Please offer some suggestions...besides getting a new post! It's driving me crazy!!! Thanks.

A couple of things to try:
Clean everything (seatpost, seattube, and clamp) VERY well. Use rubbing alchohol.

Make sure the carbon seatpost isn't scored-up. If it is, lightly sand off the gouges with wet/dry 400 spaper.

Put a small abount of grease on the inside surface of the clamp. The grease should not get on the carbon post.

good luck

Make sure it's not the seatpost/saddle clamp. I've had annoying creaks and it turned out to be seatpost/saddle clamp. Try greasing your saddle rails.

if you have to use a shim on your post, thats where the creak is coming from.

grease it up

I would clean everything and grease the shim and the creak would subside for a week or two and then start again. I greased the rails and it made no difference. I should mention that I always had trouble with that carbon aero post creeping down over time. I tried all kind of stuff to stop it but it would fall a few mm over a coouple of weeks causing the need for adjustment all the time.

Solution, I replaced the post with a Thomson setback model, 27.2 dia. and used it with the stock shim. Never had a creak or slip since. And the ride characteristics haven't changed at all. With the carbon post, I was always concerned about failure and couldn't clamp it in the workstand. The Tomson post was the best change I made on my TCR. Now I don't even think about my post and that's the way it should be.

Oh, I forgot to mention how much easier the Thomson clamp is to adjust the angle of the saddle.
