Mystery. Bianchi


Can anyone help with this serial number DS16822.. I can't find it anywhere

Just found the earlier thread, so I'm guessing Japanese 80's. Suggestions on the model would help, cheers

Bianchi or not, I would hesitate to move on a bike like that.

Between the rear brake cable/housing being way too long, the way the rear brake is being held on, and the claw derailleur hanger which it shouldn't need...there's a lot going on.

Definitely Japanese. The telling feature will be 1.375x24 English/ISO BB threading, instead of 36mmx24TPI(!) Italian threading. Seat post diameter will tell you a lot about the frame material. (Larger diameter, such as 27.2mm, is good. Smaller means thicker tubing walls, either non-butted CrMo or just regular high-carbon steel at the low end.

BB 1.37x24, Seat post diameter 28mm+, Suntour GT dropouts
Brazed cable guides top tube with routers on top of BB
No rear derailleur hanger or accommodation, cut out, uses old school breakaway and oblique washer. Double buttress, chrome Forks, seat and chain/back stays.
When did Bianchi start sourcing Japanese material.? From the serial number DS16822 can you learn when it was built?
cheers

Poor bike. I'm with the "not sure it's a Bianchi" crowd. That Bianchi sticker is a the size normally on the seat tube. If it is a Bianchi it's probally something like a mid '80s Limited. Whatever it is the Suntour dropouts mean it was a nice frame at one time. Unless it fits you and you really like it, I wouldn't put too much money into it.

28.6mm would be the outer diameter of theframe's seat tube. We need to know its inner diameter, best estimated from the outer diameter of the seat post that slides up and down inside the seat tube.

I am sure someone more knowledgeable than I about Japanese Bianchi serial numbers can help you decode the date of manufacture. Japan-built Bianchis were definitely a 1980s phenomenon.

So far I know I know they have been sourcing bikes built in various Oriental countries since the early '80s, at least for the US market. lets say anything under $500 like the SPecials, Sport SX, Classica, Premio, even some of the Brava and Limited bikes were built in Japan/Tiawan, in fact most ofd the later. All the hybridS and all but a select few of the mountain bikes, at least when I was in the businees until about '95ish

PS I believe the lack of shifter bosses and bottle mounts makes this pre '84/85 ish and if weren't for the Suntour dropouts I'd say a lowerend model.

Dating from the serial number:
D= month 4, April.
First digit 1 = 1981 year of frame manufacture.

I have pictures of another Bianchi with a similar serial number, fork and dropouts in this link:

Bianchi - identify

Biancihi Special model.

Mystery no more, thankyou. A 1981 Japanese Special
In my parts bin I have Suntour VG-T luxe derailleur and the rest of what appears origional for the model SR-Apex etc
The bike was being sold for $100 had been sprayed black and I just wanted the wheels, if I remember the front was a nice carbon. He took $50
for it and I've recently rediscovered it and off I am down another rabbit hole.
Is it junk as has been suggested or do the Suntour GT dropouts and 27mm seat post diameter infer that it could be Ishiwata 022 and maybe deserving
of the Campy I have laying around?
My Eros is Japanese SuperSet 2 and is a sweet ride are they comparable ? The geometery appears very similair.

I do not think that the frame is junk. The dropouts are very nice.

I do not know the tubing for sure but from other frame decals it may be Bianchi Cr-Mo Tubi-Rienforza.
