I plan to put on an old 105 or Ultegra RD at some point as a tensioner, but I dis-assembled and repacked the idler sprocket in the mean time. It quieted it down a lot. It was dry as a bone.
No grease. hmmm can relate; that is how i got into wrenching. My beater tandem started squeaking after we got serious riding the thing. Figured i would open the front wheel hub and see what was going on. In a word, basically nothing. Guess they just don't wanna put grease on some wheel bearings. The bearing system was worn out because of a lack of 5 cents worth of grease (makes cents
).
That's what got me to learning how to repair everything myself. Got a book and a bunch of Park tools, reworking stuff from front to back. As a kid, about all we would do was oil a chain a few times, so i wasn't privy to maintenance.
A week ago, got my wife a bike and now know better. All bearings are checked, cleaned and greased as able. The bike was basically new, but didn't matter, check anyway.
When you put on your new tensioner derailleur, post a picture. That is something that i need to do, but not sure how or where to mount the thing.
