Help Identifying Bianchi

Mckraken12

Hi guys,

I have a bianchi racing bike that ive been riding for the last 8 years. I received it in almost in new condition. It had been in a garage since the 80s.


The only identifying marks i can see on the bike are on the bottom of the frame. There is an A*6 on one side and the numbers 8095 across from it.

I cannot seem to figure out what model or year it is. I am very curious what it is. I'm not too concerned about its value because I commute with it everywhere and it is my only transportation. I plan on riding it until it falls apart or explodes. I have sunk a good amount of money keeping it up. So far I have been able to replace everything with NOS parts so it should be almost stock from how it was retired back in the day.

Any help would be great, thanks.

Does the bottom bracket measure 68 or 70mm (not including ring)?

Chorus was introduced in 1987.

It measures 70mm. What does this say about a bike?

70mm is standard Italian size, I was trying to work out which country this was made in, whether it was a Japanese one, I have never seen the head tube decal before which will either make it really easy to identify or nigh on impossible

Then again I've never seen a metalic brown Bianchi before, so maybe I need to get out more

As I said before chorus is post '87, assuming the crankset is original what is the numer code on the back, the number should be in a circle for eighties and a single number will tell you which year in the eighties (A diamond is seventies)?

Metallic poo brown Bianchi with Chorus? Almost too cool for words.

Chapeau for ownership fella.

The downtube levers and front and rear mechs look to me like Super Record from the 80s. The chainset looks like later Record from the 90s/2000s with one of the five ring mounting points on the back of the crank arm. The headset is Chorus and possibly the brakes as well.

here are some close ups of the crank and such.




EDIT:
Upon closer inspection the headset and brakes are indeed chorus.

Sorry I'm not that familiar with 80's campagnolo, I should have said that On the back of each crank arm it will say the length, date code, pedal thread in that order

Eg 172.5 41 9/16

The chainset is post-2000 10-speed Chorus with the Record-style chainring mounting bolt on inside of crank arm. You can see the marking C10 on rings. The previous generation nine-speed Chorus chainset, which I have, has the more normal five arm set-up. The dual pivot brakes are also relatively modern - they were introduced in 1993 for Record and I believe 94 for Chorus, replacing the chunky single pivot monoplanar Chorus which were introduced in 88. The chunky Chorus headset was also introduced in 88.

The back of both of the crank arms only says 2/1 0/3
