You will need a 24mm BB in the size that your frame takes. 
Old School frames will take an American BB.
New School frames would be Mid 19mm or 24mm. Made in 19mm or 24mm.
Mid is simply the size of the American BB without the Cup. So the Mid frame BB shell is smaller by the thickness to the Cup that surrounded the sealed bearing.
Mid BBs have no Cup around the bearing. The downside is the bearings usually get damaged when removed without taking tactical precautions.
