So, this is not really my "type" of bike (most of my builds are Rando style builds w/ compact cranks, wider tires and a wide range cassette) but it has fallen into my lap, it fits and I like looking at it. I've become very spoiled by my compact cranks, I forgot how much energy it takes to push a 52-42 13-23 cluster! I don't know much about it so I'm hoping to learn more about it. I've never heard of a Suntour Quattro group but this looks and works similar to a 7spd tri-color group. I've heard how lousy Suntour's indexing can be but I'm pleased with this setup. The wheels are Quattro hubs laced to FIR rims. It's a fairly light bike and even with quite a bit of mashing, it didn't flex too much in the bottom bracket.




I had a local frame builder check it out and they think the hanger was bent then heated prior to putting back to proper alignment.

Nice find!

Any ideas regarding the model? I'm not overly concerned about value, just nosey.

It is newer than my 1981 model, probably mid-1980s. I was curious to see an Italian frame with Japanese components, having previously seen either all-Italian or all-Japanese Bianchis.

52-42/13-23 was very typical stock Bianchi gearing during the 1980s. I changed mine to 50-42/14-16-18-20-23-26, which eliminated the redundant ratios while providing a useful bailout low gear.

I've never seen the Quattro group either. I am in need of a rear Quattro caliper for the bike. Currently it has a Mavic front caliper out back.

That helps! Thanks

Hello there,


you guys seem to be a fountain of knowledge when it comes to bianchi's, I'm wondering if you can help me. I have a Bianchi campions d'italia in black which i am restoring. Yet, i cannot seem to find replacement decals anywhere? I'm wondering if you have any idea if anyone online replicates or sells these decals? i am looking for the celeste decal with pink detailing. seen on the bike in this link: Bianchi Campione D'Italia - Pedal Room


Many kind regards, i look forward to a reply

Kinda interesting. In Canada, the Quattro bike actually has the world "QUATTRO" on the side of the top tube, exactly as in the velospace photo. It has a full Quattro-labelled groupset, though the components are from different manufacturers (Modolo brakes, Suntour gearing, Ofmega cranks and hubs, FIR rims).

I have three in 51 cm. One is original, one is this one I built up with modern stuff: https://www.youtube.com/watch?v=43JuEKRjBWI

So what do you want to know about your bike? It's probably from 1988 to 1990 if I had to guess.

Looks almost identical to the Campione d'Italia that I recently parted out.

The 42, 52 tooth crankset was a popular, (skinny tire) sport bike crankset then. A 40- 52 was considered a (touring) crank. Before the triple crank era came about. Likely the development of more wide range front derailers too. Chris

Campione d'italia '84 I have one

If you have a CdI with Quattro it's more like 1988 or 1989. SunTour didn't even come with AccuShift until 1987.

The progression was 144 bcd to 130 bcd with road cranks; both were/are used in racing and both overlapped time wise with triple cranks.

Here's a good article on this:

If it is Columbus Chromor, then it is a 1989 Campione D'Italia. Nice find!

I did not know the 89 came in Celeste, my CDI is black.
