Will an Ultegra 6600 (Hollowtech 2) bottom bracket work with a Shimano 105 5600 crankset?

Crank:

Bottom Bracket:

The difference in cost b/w 105 and Ultegra BB's is minimal so I'm wondering if it will work?

Thanks,

yes.

all shimano hollowtech 2 BBs are compatible with all shimano hollowtech2 cranks assuming you don't mix road 68mm or 70mm with MTB 73mm OS
