a serious amount of value in stems
If you look at the output of a stem forge, it's likely that "1mm increments" just means they've measured them and sorted into five times as many boxes as usual. A "100mm" stem is one which comes out of the forge between 97.5 and 102.5 for retail customers. Getting 1mm increments is just like the old fashioned way of assembling machines where, for example, pistons were sorted into boxes depending on how far off the nominal size they were and then selected to match cylinder bores with the same deviation.
^ watched that yesterday.
A drawer full of PRO stems in 1mm increments on the team workbus.
Nuts, and a serious amount of value in stems.
