Obsessive in the sense of being extremly liberal w/ chainlube, despite the price later extracted in gummy gritty chain and gears. Other noises, I don't think any have defeated me yet. One that kept me going for a while the other day, and possibly longer, can't quite tell if it's the same noise against a shifted ambient noise background, was my right heel apparently sliding in so my shoe was scraping on the crank on part of the pedal stroke.
