Squeaking bike

[wannaduacentury]

my husband put a carbon seat post on his bike and it made the noise worse so he changed back to aluminum and the noise lessened but it is still there. i'll try to lube up the seat rails and see how that does.

That is strange b/c I read that Giants have squeking/creaking spots on them. I was hoping the seatpost would help.

I had an giant ocr 1 that had a squeak problem that I thought was coming from the seat post. The LBS greased the seat post and it still did not solve the problem. After they did some research, he suggested the problem was not the seat post, but the headset and stem. He greased the headset and we replaced the two piece adjustable stem with a solid Richey stem and ... no more squeak! Apparently sound travels so it is hard to tell exactly were the problem is coming from. If you have the two piece adjustable stem, I would try replacing that and see if that solves your problem. Hope this helps.
