I’ve been 1×11 on 30t ring, hasn’t stopped me getting up hills. I wouldn’t bother changing if your unfit or your gears new. Think about it once you 2×10 gear is worn out. I upgraded 2010 zesty to 1×11 after the 3×9 gear was completely worn out. It’s a light bike I’m running 32t ring, Bronson I run 30t.
1×11 is simple, less clutter and great on the trails. All the gears in swift leaver move. I can see a place for 2×10 if your bike packing, long multi day MTB. Saying that I did Trans Portugal on 32t. That was a bit high, one of the top ten was on a 30t. A lot more sensible ha ha
