if you look at the bends of a 1 piece crank, you'll notice how thin and weak it looks. 3 piece cranks eliminate this weakness, plus they are lighter. another thing is, if you bend an arm on 1piece cranks, you have to buy a whole new set of cranks, whereas with 3 piece cranks you can just buy a new arm.
