Btw, check a local store. My local Performance has a 113 Ultegra (V1) on the shelf and they don't even know it.
Cool, thanks. I admittedly haven't looked hard (checked Nashbar, Performance, and Harris), but I mainly wanted to see if these had ever been produced. It seems that V1 Octalink is produced in 109.5mm for doubles and 118.5mm for triples, so I wasn't sure that they were ever made in 113. Octalink V2 is made in 113, of course.

I've looked, but not too hard, for other Octalink lengths and didn't come across any. Square taper appears to be the single cog way.
From what I've heard, Shimano Octalink BB's didn't suffer the problematic bearing life. Some ISIS BB's did, but not all.
I agree that square-taper appears to be the single cog way (and I have it on all my bikes except for an FSA compact double with ISIS interface on my "fast" road bike) but it seems that this use of old Shimano cranks would be a good way to set up a fixie. If available.
