I have been keeping an eye on my Campy 10 chain stretch since new. I just got to the red portion on the Park Tool chain checker and replaced it this morning. I also reused the master link because I didn't have a new one just yet. I removed and cleaned the pullys and put them back the same way and made sure the new chain was the same length. I lubed the chain and went for a ride. It's like I can feel the the chain clicking around the cog. I can feel it more when in the small chain ring and am not getting any skipping. Is this a matter of breaking in? I must have around 2K on this bike/ components.
