the "116mm" dimension becomes irrelevant when you switch to a hollowtech II setup.
the 116mm refers to the length of the spindle that was part of the old style BB... your new crankset has the spindle incorporated into the right side crank arm/spider...
just order a Hollowtech II bottom bracket for a 68mm wide frame.... like the one Bikeman pointed out to you.
