Difference between Boost148 and non-boost chainrings is in the offset/dish of the chainring itself only. You would use same crank in both boost and non-boost bikes, but chainring offset has to be different to accommodate chainstay clearance. Boost chainrings have only 3mm offset while non-boost ones 6mm.
