Here some photos is already made of the 2 different GERMAN wheels.
It is not only the thickness of the fins that is different. On the top photos (the German wheels), you can see that the notch between the fin and the inside of the rim is much deeper, than on the photos at the bottom.
i displayed 3 different types of rims!!!
1. German rim with 10,7 mm wide fins
2. German rim with 9,3 mm wide fins
Both of these are german with the deeper notches and the extra line on the rim bed (see photo's). This is an extra "kink" (not one angle of 90 deg, but more like one bend of 3deg and one of 87..... something in this area)
3. Normal type of rim (outside germany). with the 90 degree angle and fins ending very close to this angle)(undeep notch).
(I have 15 rims right now, the german with wide and narrow fins. and normal ones. I don't know if these also excist in different fin sizes).
5 of my rims (German wide fins) will be coated.
the rest will be sold. I believe 7 normal ones, 2 german small fins and 1 german wide fin with a dent in the middle and a dented fin. If people are interested, let me know. also if you need one or two rims. (don't know shipping costs from the netherlands to denmark).
