Just got back from my LBS shop. The guy amazed me so much I'm a little suspicous!
The chain wasn't complaining and kept falling off. Even though the cables have less than 500 miles, he adjusted just the rear derailer.
When I said I wanted to bring the bike back for winterizing i.e., lots of grease and repack the bearings. He looked down at the rear cassette and said the bike is set for the winter.
1. How did he know only to adjust the rear derailer
2. It's true that I just cleaned the rear cassette...but No grease, no repacking of bearings????
