T-Mar has made clear he is of the belief that the cambio corsa was invented in 1948, not 1933 when it was actually invented. He is also of the belief the nationalistic Italians used something other than the Vittoria Margherita. He doesn't think that Bianchi making the cambio corsa standard on their top-end race bike in 1940 counts. He doesn't think that the Italian pro peloton using the cambio corsa no later than 1938 counts. Other than Super Champion, a French ripoff of VM, there was no other competition.
As someone who uses VM and CC I will say the CC is superior to the VM, hands down.
