FYI Rear derailleur Service Campagnolo Chorus 10 Speed
When replacing the broken chain on my Seven with low miles and about 3 to 4 years old. I decided to see how the pulleys spin without the new chain mounted yet.
The lower pulley barley spun and the upper pulley moved around with a bit force applied. And that force when riding was by me. I cleaned both the upper pulley and lower pulleys Upper pulley grease had turned into gum Hard to remove. Not both have new grease and spin nicely
So if you find yourself doing some spring servicing check those derailleur pulleys
