New FC-5800 is stiffer and lighter than the five-arm design it replaces, and Shimano has reinforced construction around the chainring area to further improve the stiffness to weight ratio. The chainset uses the same bolt circle diameter for compact and traditional double chainsets, which means one crankarm fits all chainring sizes.
