campy 10 sp cassette question
Hi,
Just replaced a Chorus 10 sp cassette. Originally had 12-25, went to 11-15. I noticed a rattling coming from the top sprockets (21,23), especially using the large chainring (50 tooth, compact crank) that didn't used to be there.
Reading the tech specs, I see that the spacers between the cogs is different between the 12-25 and the 11-25. Does this explain the rattling? Why are the spacings different? How to make the rattle go away?
Thanks!
