@Wingnut, you kind of imply that you’ve seen those rivets before on other Colnagos? I haven’t. What year/models did they ever use those if it’s part of the original bike? It looks like it may have been a repair of some sort. I don’t know. I also have never seen a sleeve protruding above the seat collar, which looks like alloy, not carbon.

Hello @Calnago,

That bridge is typical of the model and period, I just think in general with regard to any brand selling a high end/price frame could do better than rivets. Be it brake bridges, front derailleur tabs or cable guides. The shim is just an aftermarket option due to the odd sizing of the seat post from my memory...

Owned a few of them and still have one.
As said by wingnut the rivets are typical of that model.

Interesting. Do you know which years specifically they did that for the bridge. Was it just a year or two in the late 90’s?

I have a CT1 with the same rivets on the bridge, was also concerned about possible repair/authenticity until after hours of searching I found a picture in a 2001 Colnago catalogue.

Of the 3 CT1's pictured in the catalogue, 1 had rivets and 2 not. My assumption is it was not limited to a year but rather something in the manufacturing process or the artisan doing the frame.
