I read rumors about SRAM increasing the low gear beyond 42T but it surprises me to see 50T. For my riding 10T-42T x 32T is enough range. If anything, I would prefer a little more top speed so I may look at a 34T chainring and a 10-44T cassette.
I think it's good to see so many drivetrain options. Gone are the days of only being able to choose 2x10 or 3x10. The 1x setups are so good that I don't think I will ever want a front derailleur on my mountain bike.
