First off, I can accurately check my tire pressure by hand because I've done it a few thousand times. I know when it's low within 10-20 PSI from experience. 2% on the Rolhoff adds to everything else. of course, you can say it's "nothing to worry about" as a response, but the numbers are the point. 2% less efficient on an otherwise 99% efficiency form of transportation over tens of thousands of miles matters to some.
Initially, yes. But not over the life of the hub. Total cost of ownership favors the Rohloff.
Not if you die of old age before going through 15 derailleurs.
That's quite a reach. At any rate, that's a potential with any hub.
YES! FINALLY! We are getting somewhere! It's a potential failure with any hub, except my hub costs $50 and your hub costs $1,500! That makes a Rolhoff or NuVinci a helluva lot less than ideal for the Ultimate Touring Gruppo...
The plural of anecdotes is not data. And a sample size of one would be pretty meaningless, anyway. I've seen many failed derailers.
Both fail, one is replaceable. At any rate, your own anecdotal data seems to guide you like a freight train, smashing through the acceptance of any logic other than your own. So, roll on...
