Gios frameset ID

[Michum]

I can pick it up at a good price. Seller says that it's a Gios but it looks suspect to me. I can't find any Gios frame that looks 100% exactly like this one. Any ideas?

Some information here about how to recognise a Gios from the giostorino.it website.

appears Belgian, and fairly low end Belgian

Flandria for example cranked out sleds such as this by the jillions

if shell 70mm in width and BSC threaded that would be a confirmation of a Flandria origin

tubeset likely to be something from Ateliers De La Rive such as Durifort or VITUS 172

check saddle pillar diameter, it will be less than the 27.0 or 27.2 of a first quality Italian frame of this era

lug pattern is BOCAMA Professional, something never employed by GIOS

fork crown is welded rather than forged, something GIOS would never employ

seat stay treatment is one GIOS never did

someone has created a "GIOS" bicycle for the price of a transfer set

sprint...in the opposite direction

Yes, definitely not gios. Thanks for deep analysis.
