Crank states what size BB for correct chainline with 68mm shell.

Do I just add 5mm to that to fit to 73mm shell? (And order a '73mm BB')?

Thanks

Is it an axle length that it states? That shouldn't change for a larger shell but you might get interference issues depending what length it is.

If you go 5mm longer the chainrings will all be sitting 2.5mm further out than they should be.
