the headset thread sparked this!

Lets produce the first Galvanic chart of vintage bicycle components.

We all know mixing particular brands will cause severe corrosion to the frame, some even self-ignite.
first sign of incorrect mixture is the paint starts turning color near the least noble component.

I know from experence French Bicycles are very happy with french components on them.
for some reason you can mix many french brands on the same french frame without any corrosion.

Italian bikes are very susceptible to catastrophic failures when Japanese components are added.

German frames seem to be very tolerant to different brands-My Nelli's Hans Lutz is ok with french TA crankset and Shimano 600 arabesque and 600 ultegra components,
I may try to put on the 600 ultegra hubs with the Italian rims, the spokes are galvanized so I hope they dont corrode, Maybe I will try stainless spokes.
I hope also the regina freewheel does not sieze to the hub,but the regina chain is connected to the french chainwheels so this should overpower the corrosion.
big risk...

but I believe we all agree which component manufacturer is the MOST NOBLE
