road bike forks

I have a principia rsl 700 road bike for about 6 years, I keep hearing a noise that I believe is coming from the frontend of the bike, this noise only comes when I pedaling while standing up. I have replaced the cranks and the bottom brackets thinking that it might have come below, i also replaced the front bearings
everything on the bike is dura-ace. I also have tightened and even taken everything apart to check everything but still hear that noise, the only that I have not replaced is the fork. the fork is a kinesis, that I believe is the culprit because it is not one piece but sleeved into the crown of the fork,(if you understand that
has anyone had also such a problem, as this is driving me absolutely crazy.

thanks for any input!!!

Just an idea that may work.

Put your bike on the trainer, one that attaches to the rear wheel. Have someone else on it and pedal hard, simulate the real world enviroment. Put your ear close to where the noise is coming from. If you have one of those hearing thing that doctors use, it makes it easier. You can also find something even better in automobile parts stores.

My suggestion is to take the front end apart and face the head tube and fork. Now carefully put it all back together taking care to grease the interface where the parts come together (of course keep grease away from the steerer where the stem clamps). Another thing to check is how the handlebars fit into the stem; if the fit is sloppy you can get noise.

Good luck.

I had a similar sound. It ended up being the connection of my left brake lever to my bars. It would slightly creak when I got up out of the saddle and put my weight on the bars.

Headsets often make such noise. If it isn't the cranks & BB, I'd look next at the headset. Adjustment may be sufficient - I wouldn't go tearing around & refacing anything until I'd adjusted (and then, if necessary, lubed/adjusted) the headset. Another likely noise source (but not in your case) is the seat clamp.
