Riky,
There are a few differences between your Cambio bike and my mid 40s
Stucchi that I can see judging by the photos. Fender eyelets and a more
relaxed geometry on your bike are obvious. Fork crown is slightly
different, head lugs totally different but seat lugs/group appears the
same. The relaxed geometry in comparison with my Stucchi helps me
confirm the aspirations of the Stucchi company as it created only a
limited amount of racing bikes and fielded teams in the late 40s in
international events such as the TDF. Stucchi were known as a
manufacturer of high quality town bikes and not really recognised as
builders of racing bikes.
I have said this before, these Stucchis are absolutely brilliant
handling bikes with as much response and feedback as an early 80s
Mexico.
