It's a bastard as they've turned out to be Hollowtech so I either return to a square taper BB and use the 105, I have, or Ultegra or find something Hollowtech.

The triples? I can see the crank bolt...
Either way, surely it's worth getting some 6400 to complete the group.
They're probably 5500, so Octalink (which I guess is Hollowtech 1). 6400 would look lots better, I agree.
