If your cranks are MTB and you want to use the 5700 BB then don't bother with the internal spacer and use the right amount of 2.5mm spacers on the cups.

Just for fullness of clarity, I believe the road and mtb bearing cups are different widths so it's not as easy as adding spacers to a road bb to make it into a mtb one.

I used to think so, but being short of BBs over lockdown made me double check and they seem to be the same and have worked the same when I've tried it.
