36 tooth Sprocket combinations

36 tooth Sprocket combinations
I get this question a lot: Q. I am running a dual ring system and was thinking of going to a 36 or 38 tooth middle ring and was wondering if I need to get a larger granny gear to go with it. A. In my experience when you change to a 36 or 38 middle ring you should go to at least a 24 tooth granny gear. I you are going to stay with a 34 then you can keep the 22 granny with no impact on shifting. We have tested many different sprocket combinations and when you try to run a 36 with a 22 granny it will work, but shifting under any load will be impacted greatly. So for smooth shifting I would suggest: 32-34 tooth paired with a 22 or 24 tooth and for 36-38 tooth paired with a 24 or 26 tooth
