Should be 2 on the driveside, one on the nds for 68mm shell

If I do it this way the chain line won't allow me to use the Tiagra derailleur, in particular won't manage to shift on the larger chainring.

I guess I would keep as it is, as long everything works.

You are right about the spacers use, as it is according to the manual. At a quick look the MTB cups are narrower than the road ones, or at leas the XT compared to RS500.

By the way did anyone tried to use an MTB crank(40/24) with road derailleur?

Yeah, I’ve run ht2 bottom brackets with the spacers in the wrong places but I’d just make sure you have the right number in there though.
