Hi @
tiredhands,
I know it is a very late response but I can't help myself as I got very curious about that Caloi bicycles sold in the USA. Do you still have the frame? I think the bike that uses this frame is a called Caloi Comp. It seems to me that the frame is the same as this at
Fixed Gear Gallery :: Jayson Eduardo's Brazilian Fixie (Caloi) , the same color, and the same bad finished thoopaste welds mentioned by @
RobbieTunes. The original components are listed at
