Help identifying mid‑’80s Bianchi road bike (serial 690646)

First time poster, so if this is in the wrong place, please let me know. Thanks

I got this bike as a free - curb alert from Craiglist (California). I’m trying to pin down the exact model and year of a Bianchi road bike I’m restoring. The bike has been spray‑painted black, so original paint and decals are mostly gone, but here’s everything I know so far. I am very eager to try this bike and will restore to a functional state. I never had a steel frame bike so really looking forward to it. I am debating whether to restore the looks (as in strip down to bare metal or see if it is possible to only strip down the black spray paint in hopes of preserving original (burgundy?) color and stickers.



I can add more photos on request (lugs, fork crown, dropouts, BB area, braze‑ons, close‑ups of any remaining decals, etc.).

Frame and serial

• Faint “Bianchi” script is still visible under the black paint on the top tube.
• Under the black, the original color appears to be a burgundy / dark maroon red in spots (e.g., near the BB and cable guides).
• Bottom bracket shell measures 70 mm wide and is threaded, so it appears to be an Italian‑thread shell (36 x 24 tpi, both sides right‑hand thread).
• Serial number stamped on the frame: 690646 (aware that Bianchi serials are not reliably decoded, but including it in case it matches someone’s records or experience).

Components currently on the bike

• Brakes: Modolo side‑pull calipers, with Modolo America brake levers.
• Shifters: Suntour downtube shifters. 2x5 speed
• Rear derailleur: Shimano SIS unit : ITM (Italmanubri) drop bar marked “ITM – made in Italy.”
• Crank/BB: Steel road crank with traditional cup‑and‑cone BB (planning to replace with a sealed Italian‑thread unit).

Working hypotheses

• general styling suggest an early‑ to mid‑1980s Bianchi, likely around 1983–1987. Italian‑threaded frame , probably sold as a mid‑range “sport/club” road model. Burgundy/red under the black paint matches several early‑’80s Bianchi finishes (various “red” or maroon models), but I haven’t found a catalog example that conclusively matches this frame plus component mix.

What I’m looking for

• Help narrowing down the exact model and approximate year:
  • Does the combination of 70 mm Italian BB, burgundy/red original paint, Modolo America brakes, Suntour shifters, Shimano SIS RD, and ITM bar ring a bell?
  • Are there known Bianchi models from the early/mid‑’80s with those characteristics?
• Any pointers to specific catalog pages or regional model names (US/Canada/Europe) that could match this bike.

Thanks in advance for any clues—would love to restore this as faithfully as is practical.

That poor Bianchi ​​rover5503 That's for the great information, although I'm not sure what you mean by Bianchi script on the toptube, though. What work have you done so far? DO the seatpost and stem move?

It appears you've found an '86 Brava in Rubino Red now disguised as a black beast. Bianchi's usual for the era Formula Two frame by Columbus with an Alle fork and Ofmega HS.

Interesting. DO you know the bottom bracket threading? can you read it off the cups? Or the seatpost size? If it weren't for the bottle bosses on the seat tube I'd think you had an older Japanese built frame that someone repainted and put '89 decals on it. Just where are you and the bike? The serial number would certainly suggest to me a Asian or other contract built bike.

First time poster, so if I did it wrong or am in the wrong place, kindly let me know.

I've got an older Bianchi that I am trying to learn something about. The serial number is stamped into the lug at the top of the seat tube - 2F 602. There is a decal on the seat tube the says "Made in Italy". There is nothing that tells me the model of the bike or the frame tubing used. Please help if you can tell me the year it was made, the model, possibly the tubing type, and maybe how much you think this bike is worth? Thanks for the help! A few pics are below.

I am not sure there are enough images of components here (assuming they are original) to help nail this down, but from what I can see, I think you are looking at something like an early 80s Nuovo Racing. Kind of like this one:



Based on the B with the circle on the seat stay, the Block B on the fork crown and the over-the-bottom bracket cable routing, I think early 80s.

It looks like a Nuovo Record RD and Ofmega headset/crankset, which would correct for Nuovo Racing (and it did come in Celeste for the year in the photo).

Nuovo racing is a mid-level, Italian-made Bianchi road bike. I wouldn't pay more than $200 for one in good shape right now, but state of the classic bike market (and bike market in general) is not working in your favor here. I have one that has been repainted in "Dusty Rose" with a bunch of Suntour parts on it (that I got for $50):



You can see the same "B inside circle" on the seat stay and "Block B" on the fork crown below.

Hi everyone,I’m looking for some help identifying the specific model and year of this vintage Bianchi I recently acquired.
It’s a beautiful metallic blue, and I’ve tried to capture as many details as possible in the photos. I'm situated in Norway and do believe this bike was sold new here.Key details I’ve noted:
Frame: "Made in Italy" decal on the seat tube. It features the Piaggio logo on the head tube, which dates it to the late 70s or early 80s.Drivetrain: It is equipped with Simplex front and rear derailleurs.Crankset: Bianchi-branded alloy cranks.Brakes: Dia-Compe center-pull calipers.Cockpit: Modolo Italy brake levers, an ITM Special stem, and Bianchi-branded bar end plugs.Features: It has full fenders and a small front rack, suggesting a sport-touring geometry rather than a strict racing frame.The Serial Number Mystery:I have searched the usual spots (under the bottom bracket, on the seat lug, and the dropouts), but I cannot find a serial number anywhere on the frame. This is making it quite difficult to pin down the exact production year.Does anyone recognize this specific component mix or paint scheme? Any insights into the model name or potential year would be greatly appreciated!Thanks in advance!

Cool Bianchi but you do know the fork is bent yes? I tSince you're in Norway I think late '70s early '80s based on the graphics may be as close as you'll get. You might look at Velobaes.com and see if you can pin down a year for the derailleurs but I suspect they are long production run ites and may not be too helpful. I'm not sure if Simplex put date codes on them or not.
