I used to own a DA 700 and had the same occurrence of noise coming from the seatpost. The solution I came up with was to extract the seatpost and wrap it with teflon tape below the instertion level. This stopped the noise and I did not have any problems afterwards.

Thanks Raysr.

Two questions:

1) Can you recommend a type of teflon tape?

2) You thinly wrapped the entire submerged part of the post, down to the very bottom, right?

Damn I hope this works, it's driving me nuts on long rides.

Tripoet,


Any white teflon tape you can pick up at any Home Depot or like hardware store will work. When wrapping, stretch the tape so it does go on thin but not too thin. Yes, it goes on the inserted section. Some tape will come up but, it is easily trimmed. It worked fine for me when I had my DA. Good luck!

I have a B2 that I use as a training bike. I had the same trouble at first with a Thompson Aluminun post. I am assuming you are using aluminum. I used a heavy grease and that would solve the problem, for a short period. I then shortened the post so that I did not have 9 inches of it inside the seat post. This helped even more. I also had a 27.2 carbon post laying around, I degreased everything, stuck it in, no more problems. Carbon is quiet! My race bike is an original Cervelo P2 and it take a funny sized post. I sure wish I could find a Carbon one for it, its like 25.2 mm. I had to buy a nashbar 25.4mm post and take .2mm off as the original 25mm post slipped as well as the Thompson one that I wasted $80 on.
