I didn’t consider that SAINT may make fold wider as front fork screwer screw will not go under it. Birdy’s fold is not entirely small so I’ll need to look into it.
My rear cassette is 11-32 so I assume it’s within range of SAINt/ZEE.
Regarding FD upgrade, my mechanic has a bicycle shop with lot’s of bikes and also is Shimano service center/seller. So he can test any configurations with any setup. I’m not going for 36 small chainring and will be using that what you also recommend 53/39. My mechanic suggested to replace chainring cranks and hub entirely. He says he will make sure chain line is fine. Do you think it will make sense or I better upgrade only Chainrings and leave cranks/hub as is?
Sorry I made a mistake of the total capacity of 28T on Saint/Zee Rd. It should be "25T".
Like I mentioned in the previous reply. Don't use Saint/Zee with a double chainring setup. The total capacity of 35T is too much for the super short RD cage to handle.
Front diff 53-39T=14. Rear diff 32-11T=21T. Total diff 14+21T=35T.
Consider going with R7000/R8000 short cage RD for 35T diff.
