Roadie Q's - Dura-Ace
Are dura ace cranks (7800) compatible with other external bb systems? aren't they all the same size in terms of width, i.e. a 73mm raceface bb = a 73mm shimano bb?
just wondering if I need a new bb for my cranks - currently FSA megaexo bb.
Also are the new 7800 cranks compatible with non-dura-ace chainrings?

All road external bb s should be for 68mm. Your old FSA megaexo bb should work fine. Also they should work fine with non DA chainrings. I would use DA chainrings or ultegra cause i think they work better than others, but thats just my 2 cents.
