I got that part, but who runs 23-25 teeth on the front chain
ring?

That is one of the two points of this particular version of the Schlumpf
2-speed bottom bracket (the other is a wider gear range than is possible
with stock chainrings and front derailers - or to wider the gearing
range where a front derailer is not practical to use).
