I'm getting a noise when I'm in the large ring and the middle of the cassette. If I shift to either side of the offending cog, the noise goes away. I recently turned the barrel adjuster 1/4 turn counterclockwise to correct slow and sloppy shifting to easier gears. It is annoying because the noise is in my favorite gear combo. Any advice? Thank you!
It is a Dura ace cassette that is about a year old. I don't ride tons of miles. I take very good care of my drive train. Proper lube, change chain at 75% wear, etc. I would think a high quality cassette would last a bit longer.
