The length of the BB spindle has nothing to do with whether the cranks will fit it. All it affects is the distance between the edge of the BB shell and the crank, which changes the chainline, so you won't be able to use that BB if you need a 45mm chainline.
Also, it has one crankset, unless it's a tandem. Crankset generally refers to both cranks.
