All this talk about longevity me thinking: How long does a rear derailer last? Since the RD gets used the most, is hanging in the breeze, and has constantly moving parts, it should wear out sooner than anything else (excepting tires & brakes). The RD on my Atlantis is the original from early '03. The logos are long gone but the invoice lists it as "Deore Silver" and Riv charged $45 for it as part of the build, if that gives a clue to the grade. It's gone at least 30k miles, mostly in a dry climate. It has been drenched and gotten filthy many times though. Maintenance consists of blowing it out with Tri-Flow once or twice a year. It still seems to work fine. Bike is 8 speed friction.
Do you guys in wet or dusty climates find derailers wear to the point of poor shifting? I realize it's going to be a function of climate, cleanliness, maintenance and mileage, but I can't recall ever actually wearing one out. And I've worn out plenty of cogs, chains, and chainrings, so it's not any maintenance magic on my part.
