2014 Trek Superfly 9.8 with 38/24

Last year I ran a 1x with 32f & 11/32r

I am not happy/used to large jumps in gearing with 38 & 11/36

What are my options?
Can I run 2x with 24 granny and smaller big ring (32? race face, etc?)

If I went back to 1x, can I simply bolt on race face 32t in place of 38t?

Ronnie, just to confirm, you installed 22T and 34T chain rings on your XT 785 cranks? I only ask because I was completely unaware that this was possible. Sounds perfect for me!
I've actually got a Shimano FC-M770 (three ring) crankset. I've got 22/34/bashguard fitted. It has the same 64mm. and 104mm. BCD as the M785. According to Blackspire on the page I linked above:

"● 22-28t & 34-40t rings are compatible with Shimano M785 and M675"

I started using the Blackspire rings a few years ago when I wanted replacement rings for a XTR M960 crankset I have and they still shift flawlessly. Also 22/34T.

While i was Doing rsearch on this i came across service bulletin from one of the chainring manufactuters Wolftooth (FOR THEIR 1x) that u could put a 32 on, but had to space out sprocket 2mm or grind a little of crank to get chain to not hit crank

I have the similar set but 24/32 w/bash guard and a 11-36 rear. It works flawlessly.

I mounted 32t Blackspire chainring last nite and going to 32t on rear (big to big) (11-32 casette) there appears to be cross chaining(?) from front sprocket that you can feel in pedal on work stand (throbbing)- shift to next gear higher (28) and it is fine.

It does have a clutch derailleur. I thought I measured chain like I usually do - rear derailleur angle seems ok. I may try adding a link later - see if that makes a difference

Any one experience anything similar?
