What does the AS on my rings stand for?

[veggieburger]

Did a quick Google search, didn't see anything. I have two Campagnolo chainrings in the bin stamped 'AS'. Any idea what that's all about?

Asymmetrical!

I am afraid to ask that kind of question for fear of looking stupid. But I've wondered the same thing at times. I have seen those stampings on chainrings 135mm for Croce d'Aune. They are also shown in a picture in the whatchamacallit database.

What type are they?
Could be "Aluminium Symmetrical" ?

Don't know what the "AS" is short for....but do know they were the first Campy rings where two rings.....were designed to work together. Memory fuzzy.....but some were designed to work with a 42, and some a 39. Maybe this is enough to jog someone's memory for the rest of the answer.

Actually Peter, I found a good picture of an AS ring. Just emailed you this link.

As 5#!+, as in "Campagnolo as 5#!+". It's a good thing
Same as AF, only in Italian.

Sent...on non ‘pinned and ramped’ rings...1994 and older...we’ll see if he is the guru...

[oldpotatoe]

Well, Dan, tech zues from Campag, NA says, 'All Size'..meaning compatible with any small ring...

[Hindmost]

But that would be: tutte le taglie

Or

.tutte le dimensioni?

I donno...:confused:

[veggieburger]

Bizarre. These are 8 speed vintage I think...didn't know they came in multiple sizes back then? Thanks for checking with the big guns.

Anyhow. Do you know...can I run these with my 10v drivetrain without issue?

'AS' = asimmetrico (asymmetric) profile, used to aid the engagement of the chain onto the chainrings, especially during extreme shifting such as cross-chaining.

Don think so..they were on 1993 and older CRs w/o pins and ramps...there were just simple big CRs, ala Super/Nuovo Record.

[Ralph]

As I said above....and my memory is fuzzy on this......but before ramps and pins, Campy had a designation re which big ring worked best with a 39 in front of it, and which worked best with a 42. It was the way it was beveled if that is correct phrase. And frankly.....didn't work all that great.....like many of the early shifting systems after friction. I just know that according to them....it mattered. And I have ridden nothing but Campy since 73.....and used to have all the catalogues that explained this stuff. Son has it now.

If we keep this up....someone will come on who can explain.

[Hindmost]

Campagnolo offered CR-era chainrings in various sizes, big and little rings. I don't think there was any indication that they were paired.

This is an image of the edge of the rings showing asymmetry? In mounting orientation, big ring on left:

Grazie!!
