I've been running 1x on my hardtail since 2010. I've never had a problem locally with a 32t up front. I have since switched to the RF N/W 34t with XT 10 speed clutch der & 11-38 XT cassette and it seems to be fine so far on our local trails. First trip through LT this year had me walking one steep section, but haven't had a problem since.

I've had the fatty set up 30t for a few months now and it's been great on the local trails. Not sure if I'll miss the 22t up front in the Winter, but time will tell.
