If you’re still curious about fitting a larger chainring on a Revolt, I finally have an answer, since I had forgot what I did… Normal spacing for a SRAM wide BB is 2.5mm on left, 5.5mm on right. What I was told to do (and has worked for the last 5 months running a 48t) is to only change the right spacer to 6.5mm, while backing the preload adjuster all the way out when install, then adjust preload appropriately. So 2.5mm on left, 6.5mm on right, while watching out for the preload adjuster when installing everything. Hope this helps.
