Please help identify this old Bianchi frame
Hi all, first post to the forum, glad to be here.
I would really love to find out anything about the history of this frame. I don't think it's anything particularly special, probably a gas-pipe tourer judging from the weight and frame gubbins, but it is great fun to ride and I love it to bits.
I cannot find a frame number or decal/logo/marking anywhere on the bike (I haven't checked the steerer). So far I have found out that it has a 70mm BB shell and is Italian threaded. This, in combination with the distinctive lugs and seat stays, and looking at lots of pictures on Google, leads me to believe it is an old Bianchi. Possibly a 1960s Sebino or Sprint? Unfortunately it's been hard to find much information on old Bianchis. I was hoping any Bianchi experts on here could help. If you need more/better pics let me know. Many thanks!

That's too olkd for me even if it is a Bianchi. I do agree though frame details especially that flat brake bridge make it a !ower end frame. It may have been built by someone for Bianchi even, if it is a Bianchi.

hello danners,
welcome to the forum and thank you for sharing your bike.
regardless of how it may have been badged when new it is clearly a chiorda product. this facility manufactured many of the ordinary quality bianchi cycles that were produced in italy; so bianchi is a most plausible identification.
the machine's frame is constructed with all agrati bits. its lugset is something called the "am" (nr. 000.8040/U). the frame's head is made by a process called bulge-forming and is part nr. 000.8046. the cycle's seat lug is nr. 022.8049. her fork crown is part of the "sport" series and is nr. 026.8058. fork ends are item nr. 000.810. dropouts are item nr. 000.8002. the cycle's bottom bracket shell is item nr. 000.8507.
are you able to read the marking on the seat binder collar? it looks to be a repeating pattern of the letters T L. is this correct? if so it is likely not original. it may be that none of the fittings she presently wears are what she came with ex-works. while fork is original/correct am not so sure about headset. originals would have been of a different pattern and frocked with a dull rather than polished plating.
have you discovered any marking on the chainstay bridge? the agrati ones of this pattern usually come through without marking unlike the similar appearing esge versions.
unable to offer suggestions as to model name as bianchi bicycles manufactured for the u. k. market differ from those we see in north america where i live.
the housing stop for a front mech cable shows us she would have been constructed with two plateau gearing. if made for the u. k. market she most probably would have come through with 27" wheels.
dating is somewhat of a challenge since we have none, or almost none, of her original fittings. latest she could be is the early 1970's.
hope this helps a bit.
