As for the BB shell (68mm wide): ID ~33,5mm OD ~40mm. I'll look around to find a set of
spacers to find one that matches, before either going medieval on the inner lip with an angle grinder or getting a BB with a longer axle (current: 127mm.)
Thanks all.
Spacers: Curiously, when I decided to space my BB out 4mm, I had some spacers I had bought once to space the cassette out (decided against, due to greatly reduced lockring thread depth), and I'll be darned if those spacer ID and OD were the exact size to space out the BB. That's gotta be pure accident, as BSA BBs predate Shimano freehub bodies by half a century.
