Stick with 3x!
Probably not what you wanted to hear, but sometimes being hip and trendy isn't the best for all of us - a bit like 150mm stems and 300mm wide bars back in the late 80's
As you mention, 1x gearing possibly works well for those who have legs like tree trunks and lungs the size of a hot air balloon, just so they can cope with not being able to select an appropriate gear in time for the sudden rise or dip that occurs just around the hidden bend...
With 3x gearing, large shifts in ratios can be achieved easily, effortlessly and....... Quickly.
2x gearing. What's that all about? Weight saving? Hardly, not when you take into account bash guards and chain devices. Like 1x, it removes a gear shifter from the bars that can then be replaced with a dropper post remote! Like 1x, 2x shares the same inconvenience for most of us that our bike becomes totally useless on road sections or even, dare I say, going remotely downhill because the highest gear available is 38:11, as opposed to 44 or 48:11.
Oh, maybe I need to buy myself a road bike to soothe my need for speed and wind in my hair, flies in my teeth?
This forum is often filled with talk of industry conspiracy when it comes to wheel sizes. IMO, a choice in wheel sizes is a good thing. The real industry con that is being trotted out to the masses is this apparent need for mountain bikes to have fewer gears and become less adaptable or mult-discipline through telling us that we need to have only one or two rings at the front! It's total bollox, but at least you can all go and spend more money on converting your once very useful and adaptable bike into one that is good for a little less. Oh, and don't forget to go off and buy a road bike!
So, please, I'm not a closed minded individual. I will gladly listen to any proposed advantages of 1x or 2x gearing that people come up with that they feel genuinely have helped them enjoy the sport more than they enjoyed it with 3x.
And please, advantages, not the usual justifications after having shelled out a load of hard-earned luka on an 'upgrade' that the media said was going to make me a happier person.
Mild rant over, sorry to the OP for kinda hijacking your thread, although hopefully I may have helped you make some kind of decision, that following the flock may not be in your own personal interests every time.
And it is a beautiful sunny morning
EDIT: The smart money will be on the majority of recreational riders going back to triples within the next 2 years...
