Masi Gran Corsa components
Hi Folks,
I recently acquired a Masi USA Gran Corsa need help identifying the components. It apparently came with a Campagnolo group. The headset, crankset, brakes, front wheel (Omega label) & front


derailleur are all labeled Campagnolo sans model designation. In a box of extra parts was a Campagnolo RD that has the same metallic charcoal gray color as the FD.
The info on the BB is: 58 with a “C” underneath on the left, MASI in the middle & the number, 8367 on the right. The back side of both crank arms has 31 in a box. The NDS arm has a 1 on it & the DS has a 7 on the spider.
To further confuse things, the previous owner “upgraded” the gear train and shifting to Shimano STI 105 9 speed.
Any help identifying the component model would be greatly appreciated. I’d like to return it to its original state.
Thanks & regards,
Van

Right off the bat seems like a Campagnolo Athena RD in graphite.

coating of some sort.
oh, how the mighty had fallen
the subject Gran Corsa has a different lug set and fork than others I have seen. So it goes. Sublet to Italy somewhere and brought in and painted here - most of them.

Hi folks,
Thanks for the info. I’ve gotten a couple of short rides on it. Works well, but I’d like to get it back to original setup. Will ride it as is while collecting parts. Any ideas on the year?
Thanks & regards,
Van

...I might be wrong, but in the years I was more familiar with these, they were sold as frames. Then built up either by a shop or the owner according to preference.

They did sell component packages, after the whole gruppo thing took off.

If I had to guess, your original owner opted for an Athena package. Not sure I'd sweat returning it to original, but that's just me. I probably would lose the brifters, but again, that's just me.

In the 80’s the whole line was available as a frame set. Gran Corsa, Nuova Strada, Gran Criterium and 3V Volumetrica.

Eventually the production of Masi frames went to Mondonico, and the build quality was excellent, covered with California-applied paint by Allen.
My recent Gran Corsa frame acquisition seems to have angles at least as steep as those listed for the Gran Criterium.
The Athena rear derailer shown was more widely sold in silver, can use Syncro-7 levers and shift quite well over a 13-25t freewheel if the correct indexing ring is used in the right-hand lever.
