I’ve been wanting to move the gearing on my Santa Cruz Nomad down a touch from the 32T x 11-34T range I use most of the time without having to bother with the 22T granny ring. I found 2 options for 30T chainrings that are 104BCD.
Click on either image to jump to the vendor’s site. I’ll update with impression from whichever I end up using, but I thought I would share these rings with anyone out there who would like something slightly smaller than 32T on the front. of their 104 BCD cranks.
