    You need the FD for 42/28. I can't remember where I read it though. I'll have a look and see where I found it but I'm looking to do a similar thing.

    does your frame use the direct mount front derailleur or the normal clamp on front derailleur? if clamp on, there is no specific 26/39, 28/42. there are only different ones in the direct mount derailleurs to get them at the right height for the chainrings.

    You`re right, it`s S3 direct mount.
