Old and hopeless
If I could have bought my new bike with a 2 by (32/22) with front derailleur and a 10 speed (11/36) cassette and no PF BB, I would have been all over it like a cheap suit. Honestly, I loathe 1 by.I know how to move 250+ grams off the cassette and towards the centre of the bike, whilst increasing the range of gearing from 400-500% to 600% or more. It's called triple chainrings and a front derailleur.
Back to the gearbox, or cassette box, or whatever they come up with... it is clearly better to centralize the mass, take the stupid unsprung and rotating mass off the back wheel... but in my personal life, I am not an early adopter, and I will wait till the bugs are ironed out. Being so frickin old, I may miss out.
