I don't know the difference in width between these cranks in triple vs. double.
I can't find anything on Shimano's website.

I have two Shimano Triples (Ultegra 6603 & 105 5603) and two Shimano Doubles (also Ultegra & 105).

The Triples have a substantially wider tread than the doubles. My triples are equally wide, I would assume the 5703 is the same Q factor as the Ultegra 6603
