Need 120BCD 36 tooth for 2x10 setup
I have a 2X10 setup that I like. My current large chain ring is a 39 tooth. I want to downsize the a 36 tooth that will fit my 120BCD setup but all of the rings I can find are Stop Drop that will not work on a 2X setup. Does anyone make a ring that would work? Thanks

Is is 120/90 is are both rings a 120 BCD? I guess we should also know what cranks you are running? I know FSA has 120/90 for their stuff and they do 34 and maybe lower in 90bcd but I don't know about an actual 120bcd that small. I know for 130bcd generally the smallest is 38t generally (though I have read rumors of potential 37t but haven't seen one in real life).

It's currently a Sram BB30 setup with a 120BCD large chainring and a 26 small. I don't know the specs on the small but it shouldn't matter, I'm only interested in changing the large ring. I see lots of 36 tooth 120BCD rings but they are for a 1X setup with wide/narrow teeth that wont work with a 2X setup as the shifting won't always line up with the different teeth.

Zeus cranks were 120mm BCD with a 36T minimum tooth count, but those rings are scarce as hen's teeth these days.
