My only complaint to new standard is that the manufacturers abandoned the old standard.
I wish I can still find new 9 or 10 speed XTR shifter, derailleur, and cassette for my steel XC; but nothing is available , not even on eBay :-( Shimano can easily implement new shifting technology into old standard 9 speed, but they choose not to... probably because they can't make enough profit.
Manufacturers, please no more new stardard on BB, Headset, and hub spacing. Not 13 speed either. We had enough of them already. New standard will only drive the price up on BOTH new and old standards.
