I found a very nice little Bianchi for my wife...she loves it.
It has some very cool older matched campy gruppo. All the parts are polished, no flutes with a single stamped logo. They are all more artistic than what I have seen in the various websites. The bike appears to be mid 80's and the hubs say "record" and it is a 7speed freewheel.

Momma wants to upgrade the shifters to an "STI" style but keep the look of the components.

SO, can anyone tell me how to date and ID these components?

1oldroadie,
to start with welcome to the forums.

Your wifes campy components should be stamped
with a date. I'd look at the inside of the crank arms
for example, my crank arms sat PAT84 which is
consistent with my 1985 bike.
Or on some older components BREV73
from the italian BREVETTE is italian for patented.

Most of the components have that or
a symbol (diamond, circle etc.) with a number in it.
for more info on campy components see www.campyonly.com

hope this helps,
Marty

Campy 7spd used a 5mm cog spacing, so 8speed compatable Ergoshifters will most probably work, but check further.
Try the Campyonly website.

They have micro-indexing for the front mech, so will handle anything.

I've looked on every part of the bike and can only find marks on the crank>>>170 and a 42 inside of a square. But there are logos on everything

Look on the top of the rear derailleur where the cable and housing go into he top, you'll see the letters- pat ( also stands for patent) and two numbers, the numbers refer to the year the derailleur was made.
It sounds like you have a "C-record" Gruppo (if the finish on the rear deralleur paralellogram is smooth) from the late '80's maybe '90 or whenever they quit making it and came out with Record and Ergo in 92?
If the rear derailleur appears to have it's logo cast into it with a sculpted finish, it's probably Nouvo Record, 60's to late 70's early 80's .
If it has any black anodisation on it with a smooth finsh, it's Super Record, early- mid 80's to late 80's.

I have read in a website I can't recall the company, about these people buying back old campy bike set up, I just can't remember who was trying to buy back this bike with campy set up, and I am very sure that it was like a couple of years ago, I suggest try surfing the internet, before you start removing the old campy grupo, You might be holding a good mine

The older stuff is difficult to find. One bike shop that seems to have a lot it celoeuropa - 949-643-1620.
I recently upgraded my 1985 DeRosa to DuraAce. Originally, I had Campy SuperRecord (back in 1985, the DeRosa SLX cost me $335 brand new, and the full SuperRecord gruppo cost me $315), all I wanted was to do was to add a gear from Ultra7 to 8. I found out that all the new 8/9/10 speed stuff uses a new technology - I needed wheels that could handle a cassette vs freewheel. I then needed a new rear derrail. that would handle the extra gear. But the rear derrail uses a new type of shifter tied into the brake levers. So I needed the brake levers and also new brakes. Since brakesets come in pairs, I also needed to get a new front derr as well as a new crank and bottom bracket. I ended up with having to buy a WHOLE new gruppo just to add 1 more gear. Technological progress I guess
