I'll tell you what I know which isn't f&^k-all, really.


Yes, there were Colnago Saronni's made after he won the Worlds in 1982. But there is a lot of conversation about whether they are made by Colnago or BMZ made them. Biemmezeta made frames of high and low quality for a number of builders, so it's not without reason. They also used aero tubing Biemmezeta Aero' which most folks consider Columbus. They sold nearly everything under different labels.

Your frame is missing the Saronni headbadge and most Saronnis had "Saronni" cast into the seat stays at the seat tube cluster, not "S". But that doesn't mean they didn't change somewhere down the line.

Most people say the paint is fragile-- as is yours.

Your fork crown is definitely a Saronni fork crown. Those would be really hard to fake.

You can buy the decals, so it's not impossible to fake, but your frame has a lot of the right sort of wear.

Colnago hardly every used three braze on brake cable guides on the top tube and almost never that sort back then. See the two in the photos below.

I'd bet you have a real Colnago Saronni, whether it was manufactured by Colnago or not is another question, but BMZ built a LOT of frames for a LOT of marques.

The only question is: Saronni's came in high end and low end models. Which do you have? Given it's aero and no one thinks that BMZ drew their own tubing, you should have a high end frame and that should be Columbus.
