Pick up a Campag race triple, they still use a square taper,
BB: 111 symmetrical [115 if fat seat tube on frame]
2 models 52, 42 or 50,40 for the outer 135 bcd.
3rd ring is a 74 bcd . so stock is usually a 32 or 30,
I fit a 26 on my 52, a 24 on the 50.. half the size of the big ring ..
I'm just a tourist rider..
You need a longer arm RD, to wrap up the slack chain,
the parts for that longer arm may be retrofitted to your existing derailleur,
I got a short cage RD from their MTB era, bought the long cage bits
NB, it was 20 years ago.. Campag is rebuild-able, they sell the small parts.
somewhere .. Ask Dealers of pro level bikes..
the rest is just a clean and lube maintainence ..
Campag makes a freehub driver for their hubs, to adopt shimano cassettes,
consider that. its a C note at Cambria bike..
