Are you using three chainrings or two? What positions are you going to put them on? If you are going to use a chainring on the inner (74mm BCD, “granny”) position and you use a 110mm BB spindle, I bet the front derailleur will not have enough inward travel to make the shift. (It’s been a few years, but I tried this. It didn’t work.)
I’m using the middle and the granny, and put a chain guard on the outer. I went back to using the 113mm cup and cone bb, and everything looks like it’s lining up well. But, I just found out the 9 speed cassette I bought needs a spacer for the 8-11 hub I have. I’ve built a half dozen or so fixed gears, but this is the first geared bike I’m doing. Just trying to enjoy the process! I guess I’ll be back with a future question or two.
