Ultegra 10 speed triple 6703
- I don't have one but in investigating for my triple 6603 cranks and again for my double 6700 cranks, I found that the BB options are quite flexible.
You should be able to run with a BB-7900, BB-6700, BB-5700, BB-5600, BB-4600, BB-7801, BB-6601. (there may be some different prefices in their naming convention e.g.
they call it SM-FC6601 but I called it BB-6601, but if it's a bottom bracket of these numbered series, it will work).
Your mention of a BB7700 on the other hand should not work - that was the 9-speed DuraAce BB which has a very different form factor than those I mentioned.
