Note to self: don’t make jokes on here, some people take it seriously 😉
Actually, yes – for most Rohloff builds I get the chainline as straight as is reasonably possible, but for some it’s not possible to have a dead straight chainline, and it has no effect on performance. Derailleurs manage fine without a straight chainline.
Middleburn do, and it’s lovely – and there are other Rohloff-specific chain sets – but they’re really single-speed chain sets of the right size with the chainring in the outer ring position. There’s no magic about it, Rohloff designed the hub to have the same chainline as the big ring (if you use the 15,16 or 17t cog).
