QUESTION... the marketing spin is so enthusiastic about the low maintenance required of the Nexus hubs... but how long do these things last? How many tens thousands of miles before you have to overhaul or replace? And how much would it cost to overhaul or replace? And who in the world even knows how to overhaul these things? I mean, they're probably damn complex inside.
What I am saying is, let's not get too hasty about cheap derailleurs & cassette systems that are poorly maintained and therefore don't work properly. They're open to the weather, yes, but it's also open for you to work on, no? And if you don't like the Sora derailleur on your entry-level Sirrus, you can always upgrade to a better group. If your cassette goes bad on your derailleur bike, it doesn't cost much to fix it.
If your wheel based on a Nexus 8 goes bad, are you facing a replace-the-wheel or replace-the-bike kind of decision? Sort of like when the non-standard, proprietary motherboard on an out-of-warranty PC goes bad?
I can see a Nexus 8 as a good decision for a bike that hardly ever gets used. The user will never take the rear hub to the end of it's lifetime. But if you're putting 5000 miles per year on the bike, is this a good technology for you?
Another thing with these built-in lighting systems. LED technology is changing so quickly, sort of like a Moore's Law evolution of brightness over time... why would you want to strand your bike with proprietary lighting technology obsolete that will be obsolete in 6 - 12 months? You'll have to do surgery to cut the proprietary light off, then find the next generation light for you that matches the voltage put out by your dynamo, then do more surgery and soldering to feed it with wires to your dynamo hub instead of batteries, gosh it's just too much hassle. Again, it's a great solution for non-challenging applications, but if you are a real commuting road warrior, and you want to keep the best lights on your bike so that your safety keeps improving, then you don't want to be locked into a lighting solution, either.
