De Rosa SLX: Professional v. Primato
I have a De Rosa Professional with Columbus SLX, mine is from about 1986.
What is the difference in geometry and other features when comparing the Professional to the older Primato?
I'm considering acquiring a older De Rosa with SLX, this bike features a flat crown on the fork.
When was the Promato introduced? What differentiates these these two models? What is the difference in performance or ride/handling?
How does an expert know if it's a Primato or Professional?

How much older is the the other bike with SLX? I believe SLX kinda came out in 84/85 so there might not be much difference there
If the newer bike is EL OS it should be a lighter frame and might feel a bit stiffer

Did De Rosa produce any other model with SLX and a flat fork crown, or was the Professional the only model built from SLX?

The Primato is a bit more laid back in geometry than a same sized Professional. I may have geo charts somewhere. I'll post if I find them.
I'll see about measuring mine. I have a 54.5 of both hanging in the garage.

I recall seeing SLX being on larger bikes. Thicker and heavier but stronger. Cannot support that though.

I recently picked up this '86 or so Professional with SLX tube set. It is a 61.5cm frame with flat crown and no chain stay bridge.

I believe [MENTION=61463]gomango[/MENTION]'s wife had an SLX De Rosa that was labeled a Primato, not sure of the geometry on hers.

TSX and from I can tell, it was a Nuovo Classico.
They were repainted as a batch for a local racing shop.
Apparently, all they had at the factory were Primato decals.
It most certainly is not a true Primato, but it's still a beautiful bike and she loves riding it on occasion.
I'll measure it later and add to the thread.

I think the correct take away is that a Primato, by definition, is EL OS tubing. Personally, i think the Primato is a much more interesting, beautiful bike...and I like how my Primato rides more than any other De Rosa I've had.
