|strange drivetrain noise||dash|
Jul 4, 2001 3:31 PM
|I have a new bike with 2001 campy record 10v (12-25 Ti/steel cassette in the rear). everything worked fine until a couple of days ago i noticed a strange loud noise when pedaling hard in the fourth cog from the right (i.e. 15 teeth cog).
the noise persists in either 39 or 53 chain ring, but the drivetrain is silent in all other gears.
I checked rear der. adjustment and it is perfect and the shifting is not effected at all - smooth and quick.
any ideas as to what can be the problem would be greately appreciated.

the cogset was too loose, i just had to tighten it.
