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!!!
