Question #1: Hopefully, I have the terminology right. But the links to the photos (http://mytruealterego.blogspot.com/2...-problems.html) will explain in pictures. The first photo shows the part that I am talking about (circled in red). When I am on the smallest chainring and the smallest rear cog (as shown in the second picture) the little flange is touching the top of the chain. I was wondering if anyone knew what to adjust. I just changed the rear cassette (only).
Question #2: While testing the derailleur on the stand after changing the cassette, I was turning the crank with my hands and noticed that when I am on the largest chainring and smallest rear cog, I feel a little bit of roughness (like bearing grinding or something like that). It goes away once the chain is moved away. Any idea what this is about?
