preparing to put on an Athena groupset, I found myself staring at three Campagnolo rear similar-looking derailleurs wondering "which is which and what's the difference?"
In the photos they are marked, from Left to Right, "Athena", "Avanti" and unlabeled (just "Campagnolo")
The one with the groupset does not have a model marked on it. Just "Campagnolo". and it is the RH one in the attached pictures.
The other two (from my spares drawer) are marked "Athena" and "Avanti".
Now, I always understood that Avanti was kind of crap stuff and that Athena was better. But construction-wise they look very similar.
And then the unlabeled Athena (RH image) looks quite different from the marked Athena (the flange bit in particular, which looks similar in style to the Avanti but is a different shape.)
I don't have a scale here, so I can't weigh them to see if the difference is there but can anyone shed light on the differences here if any?
was there any evolution from Avanti to Athena or vice-versa?
