Fun fact: Sturmey-Archer introduced index shifting in 1903.
Yes, but that was in Europe (whatever the Brits may think), the First World when it comes to cycling. But if I were in America, I'd be extra careful.

IME the only thing you really want when using an indexed system is some form of cable tension adjustment in the system. At the RD will do nicely, and at the DT cable stop is even nicer as it enables adjustments without losing momentum. Both are pretty much standard. If not unavoidable.
