Any question answered...

Slow reply, but the measurement you want is the flat, unthreaded part of the spoke just before the thread begins. When the threads are rolled (and on good spokes they should be rolled rather than cut) the recess is effectively narrower but the raised part is effectively wider, hence the larger measurement on the thread itself.

^^ Looking at the Alpina stuff I think all their spokes are either 2.0mm or 2.32mm at the thread end.

Thats great, many thanks mate.

I went with the unrolled measurement in the end as you suggested. 13G it is.

I'm pretty happy with how accurate my micrometer is. It is about as old as a metric micrometer could be and is easily accurate to one or two hundredths of a mm still.

When I first got it it was way out. I thought I needed to calibrate it but it turned out I just needed to clean some corrosion and dirt off the contact points. After that it has been pretty much perfect since. I've got a cheap digital micrometer and whilst it is pretty good it is comparatively inconsistent.
