Firstly - thanks for all the information, pictures etc - today sees my first posts on the forum, although I've bee watching for some time.
I've recently acquired a Cerbai `Special' bike and a Giai frame and wondered if there are any other examples or information out there.
Both companies still exist - Giai of near Turin appear not to make bikes these days, but still run race teams and claim history dating back to 1911. Cerbai of Florence seem to sell mopeds!
There Cerbai (and my other rides) can be seen as photographed by the vendor here:
Does anyone know anything about these brands?
