Bought a vintage Bianchi made in Japan I nearly did not buy it as it looked too far gone I told him bike was basically scrap and he should donate it, so I thought in terms of the glass is half full I looked at the good parts he said wheels where 27 inches and at a glance they looked like 27 it had superficial surface rust in quite a few places, tires are perished.
He wanted $50 and I offered him $20 that was an insult, then $40 cad I nearly walked away then he showed me the leather saddle in very good condition we settled on $45, the saddle sweetened the deal
I was thinking I should not have bought it on way home.
Soon as got home I started cleaning with SOS pad for about an hour and I was amazed that 99% of rust is gone
one of the reasons I bought it was because of the 022 light frame
The seat tube seized does not bother me as once I had a bike and seat tube was a bit big I thought if I can hammer it down to correct size it will be OK it would not go down so I got a bigger hammer and an even bigger hammer
still not correct so now I had the job of getting it out. I have a slitting grinder to make a groove in the back
after cleaning I found wheels are 700
it's a 25-inch frame correct size for me and everything is straight,
never seen brakes like this before, brake pad is missing from rear
I think it just needs seat post new tires and cables, chain maybe different rear derailer it has a long cage and a few more things
no play in Sugino triple cranks and teath and BB look good. wheels are true. it did not look like this before I cleaned it
I was thinking on the rear wheel stays some paint is missing and it looks chrome underneath it would look good all chrome on stays if it's possible to get paint off

Any advice would be welcomed
