So I dragged home an Allitalia bike a few months ago:



It has an interesting bike boom era mix of parts. Suntour Cyclone derailleurs, Sugino Super Mighty cranks, KKT pedals, Weinmann brakes, Jim Blackburn rear rack.

The hubs and rims are so dirty I have no idea what they are, Front rim is steel and rear is alloy.

It's surprisingly light.

I want to use the cranks on another build so I pulled them. Since the bottom bracket was in much better shape than other parts I have, I pulled that too.

And scratched my head a good while.


The cup says "O.M.A.S Italy" and "36 x 24F"

Neither side is a fixed cup, they both have lock rings.

Sealed bearings that are still smooth:




The spindle is a very high quality piece of machining.

Why on earth would a bottom bracket this nice be in a brand of bike I've never heard of?

EDIT: If any of the hive mind here know anything about Allitalia bikes, I'd appreciate it if you shared your knowledge.
