70’s Bianchi Sprint - fixie build

[sparkybhp]

Calling all resident Bianchi experts - anyone know what date/model I’ve just bought??

I can and will upload more pics in due course but I’d love to have a bit more info if anyone can help?
Thanks

Got this stripped down this morning, Paul brake lever and Nitto bar end plugs were nice loot!

Bottom bracket actually felt pretty smooth but I took it all out anyway for inspection and re-grease, good job I did!

Bb and headset both cleaned up well, love how the bb is Bianchi branded - classy!

Reassembled the frame and gave it a thorough clean and t-cut. Before:
After, put some new inner tubes in the wheels it came with and added the 3ttt stem and some cr-mo flat bars. Not 100% sure on the direction to take this but think it might be flat bar and fixed:

So that Paul lever will be handy then.

Update: I’ve done a bit of research and I reckon this is a Sprint - I’ve changed the title accordingly. Still pretty sure it’s mid-seventies, it’s got the nice Bianchi stamped rear dropouts. I think later on they went to really cheap looking flat steel dropouts. Happy to be corrected/further educated though!
Got this to the stage where it’s rideable with a rear wheel rebuild and new chain.

Also fitted some lyotard rat trap pedals I’ve been saving. I’m loving the way this is looking and it rides really smooth too. This isn’t the final stage, I’ve sort of got it in my head to move the components and wheels off my Koga Miyata s/s bike to this and then redo the Koga with some period Shimano 600 parts and some nice old Mavic MA40 wheels I recently got.

Smashing!

Sorta finished now, decided to add a freewheel and go single speed rather than fixed. Had a Halo Clickster 16T which I’ve put on, lovely and loud when coasting.
That meant I had to add a rear brake so I’ve fitted a matching pair of weinmann 500 callipers and swisstop pads. I’m desperate to find a matching l/h lever for the Paul that’s on there but I’ve chucked a cheapie on for now. The white cable outers and top tube clips came today so I’ve tied it all together for now.
I absolutely love this bike, it’s beautiful with nearly 50yrs of patina - even has an Italian motorcycle/scooter shop sticker on the down tube. I’d love to know the history of this one, bet it’s had an interesting life so far!
