I drive the same Rohloff for over 8 years and do not see an end of its lifetime. I cannot speak for other brands, but in all posts above the free-of-charge service by Rohloff, as part of their special corporate culture was not mentioned. Up to now, whenever there was a problem, the thing was being send to Rohloff and I had to pay nothing. That being said, ...

My main road bike has campagnolo gran sport derailleurs. That was mid range when I bought it back in 1980. Probably over 100000 miles by now. I have replaced cables and jockey wheels a few times but it still shifts great.

Derailleurs will last almost indefinitely. The jockey wheels will wear out in time (tens of thousands of km) but the rest of the mechanism shouldn't see significant wear.

Go Singlespeed or use an Internally geared hub to avoid the problem entirely. May need an eccentric bottom bracket or a bike with horizontal dropouts to pull this off without adding dangly bits like a chain tensioner. However, chain tensioner a tend to sit a bit further out of the way and are less likely to be damaged.

The derailleur is, unfortunately, one of those critical parts that is very hard to protect from damage; without sacrificing another part. As Batman pointed out, you can purchase small hoops that attach to your frame and offer some protection. As he pointed out though, these types of products might protect the derailleur to some degree, but you risk ...

They make bash guards for derailleurs which mount to the frame which protect a derailleur in a crash like but these are dangerous in that they transmit a hit to the derailleur to the frame (and frame damage is typically less repairable/ more expensive than a derailleur damage). Usually, what gets damaged in a crash is the derailleur hanger, which can be ...

If you compare new and old derailleurs, you'll see that the new ones have cages made from thinner metal, but stamped to make them torsionally rigid. Older ones like this Campagnolo FD have a nice flat low profile cage that works well with cranks that resemble the older Campy with low Q-factor and relatively straight crank arms. Of course vintage ...

There will be only very small differences in the widths different FDs (assuming you are talking about the inside to outside dimension). One that is designed to be minimum sized so that it provides a best fit for 46t large chainrings is Shimano's CX-70, intended for cyclo-cross: ...

You need to loosen the screw that holds the cable and pull that cable out a little bit. The limiter screws that you've used so far are rather used to prevent the chain from falling off, and it's a finer tuning than you appear to need now. Thus it would be useful to level them out before pulling the cable. After you adjust the cable, take a few minutes to ...
