Thanks, Steve, I'll check it out.
Stopped by the LBS to use the crank extractor. Slapped the chainrings on and hit the road. Oh, I didn't abuse the LBS by doing this. As a matter of fact, they would have installed the new ring for me since I bought it there, but I wanted to do it. AND I had them order an extractor for me so I can start pulling the rings for regular cleaning. I hardly noticed a difference in shifting. I used an Engagement Ring brand. Uniform teeth and no ramps, pins, etc. The nice new 39T ring made me faster, too, which I can't figure out since I was on the big ring all the way home.
Stopped the chain noice, too, from the worn teeth on the old ring.
So Yorick is running silent again except for the buzz of, I guess, the pulleys anytime I am using the big ring. Is that normal? I don't hear it on the middle ring.
Regards,
Raymond
