External bottom bracket cup size - jeez!

[DKFan]

So a few months back I bought a BB93 BB not realising that the cups were smaller than ‘standard’ external BB cups that I’m used to
Oh well, I’ll get a Park BBT-29
This morning I’m fitting a MT800 (XT) BB 16 notch and guess what - slightly larger diameter and I need another tool
The worlds gone mad!
