Hey folks! Im new here! I have been riding bikes for years, but not very knowledgable. I have acquired a Bianchi last year and am only doing some research now on it. I believe it was built in Japan, due to the Shimano parts, but I am struggling to find images online of the bike I acquired. It has a unique emerald green colour to it (not the traditional sea-foam green). And the serial number is CS481165. If anyone could help in any way, would appreciate it!

Welcome to forums. Your Bianchi was manufactured in Japan during March 1984. Given the source and Shimano components it could be either an entry level or mid-range model. We'll need more info, such as the models of the Shimano components and tubing material (if there is a tubing decal). Of course, a good set of photos can supply all this and more. Ignore the forum warning about needing 10 posts to upload pictures. They won't attach to the post but they will upload to a gallery album where members can view them.

Hi all--I just purchased what I believe is a 1988 Bianchi Sport SX, made in Japan. The serial number is AS718256--any way to verify?

Thanks all! Amazing work in this thread...

Welcom to the forums. You were close. It is Japanese manufacture but it's from January 1987. The serial number does not include codes to identify the model. You have to determine that from a combination of the tubeset, frame characteristics and/or components.

Hello all, I am about to pick this up and was wondering if you all could give me a bit of info about it? As you can see it was repainted.

The frame is a 1987, Italian manufactured, mid-range model. Given the repaint and rebuild, it could be one of about five models, with either a Formula II or Formula II tretubi tubeset. The shift levers and calipers appear to be very early 1990s Shimano 105SC.

Thank you T-Mar. Would there be anyway to narrow it down? Or get the five models you mentioned?

The three full Formula II models were the Trofeo, Nuovo Alloro and Limited. The two tretubi Formula II models were the Squadra and Campione d'Italia. Typically, the tretubi models didn't have the embossed stay caps and fork crown, so I'd be leaning towards one of the full Formula II models. To the best of knowledge, the frame on these three were identical, except for colours. The difference was in the components, So if it's been repainted and all the components have been replaced, there is no way of telling. Sometimes, owners retain some of the OEM tertiary components, such as the headset, pedals, seat post, saddle, bars and stem. In this case it looks like it even has a replacement 105SC headset and the saddle is definitely non-OEM.

I heard the brake bridge can help also narrow it down, the saddle is a Selle San Marco Rolls

The confirmed 1987 Bianchi Trofeo, Nuovo Alloro and Limited that I've seen have all employed the same investment cast brake bridge as used on your frame. Given that the frames are otherwise identical, it does not make sense to vary something as trivial as the brake bridge. Using an identical frame for all three models has advantages from both logistical and cost perspectives. If someone has seen a different bridge on one of these 1987 models, it was probably due to supply issues with the specified bridge or a Bianchi manufacturing issue.

Hi everyone. I am new to this forum. I am considering buying a vintage Bianchi, but I don't know what model or year it is. The serial number is 8L 4042. Would anyone have any idea what the model and year built. Or where can I find the info.

Welcome to the forums. The S/N does not include coding for the model name, nor does it tell us the exact year. However, it is a Italian manufactured model from very late 1978 or 1988 and should therefore be a 1979 or 1989 model. We should be able to determine the model and decade from frame characteristics and components. Please post pictures. Ignore the site warning. Despite your not having the required number of posts, photos will upload to a gallery album under your user name, where members can view them.

Thanks T-Mar. I tried posting pictures but they don't appear. Can you have a look at the gallery and let me know what you think

I had a look at the pictures. The decals are 1988 to 1989 and the frame features are consistent with the era, so it would appear to be a 1989 model manufactured in late 1988. Unfortunately, there are some modifications that complicate identification of the model. The brakeset is an obvious upgrade and despite the presence of the Forumla II decal, the fork also appears to be a replacement. The drivetrain, assuming is OEM, is typical of a Canadian market Campione d'Italia.

Sn: As316717
 
I am checking a Canadian Bianchi bike which SN is AS316717. It comes with Shimano 600 groupset. I believe that is is from Japan. Can anyone tell me what year and model is this bike please? How much does it cost now? I guess it is a blue 1985 Giro. It looks almost the same as the catalog except that it is Shimano groupset.
Thanks

Benny

Welcome to the forums. Your Bianchi was manufactured in Japan during January 1983 and therefore is a 1983 model. I don't know what this model was called, at that time. Value will be highly dependent on the cosmetic and mechanical condition and where you live. Consequently, we'll require photos, to properly assess the first two parameters.

Hi Guys,

A question about a Bianchi serial number. The bike appears to be from the early 1980's (perhaps late 70's). Serial number is: GL28281? Or it could read 6L28281. The serial number was on the head tube (nothing under the BB). Or is this just a part number for the head tube?

My guess is that this is manufactured in Japan?

Given the serial number and location, it should be a 1977, Italian manufactured model. Please post photos for identification of model.

I'd place the value at $250-$500, depending on the market.

Hi T-Mar,

Thank you for your reply! A few pictures of the bike below. Note that it has been repainted and stickered - apparently faithful to the original (although for sure the celeste is the wrong colour...).
