On the photo the 25mm rim on the left and the 19mm on the right. I measured with two wires, simple but good enough for a quick comparison.
The allen key loosens the bolt that keeps the wheel on the drumbrakes' axle.
Okay, so we loosened several items and now with some jiggling, it's possible to lift the drum from the brake. You have to get the damned thing over the terribly long axle, which at first sight seems impossible, but it is! It's such a tight fit that even the width of the 5 mm thick brakecable has to be manouvred out of the way to push the strut competely against the inside of the wheelbox.
