Interesting article, I knew only the xenon from the 2000's as being a mid range product from campy being lesser than mirage in terms of quality, I didn't know that they had one in the late 80's. I guess it would be a match for RSX or RX100 even though it didn't have the smoothness and precision of shifting of those.

Before Avanti, Xenon Synchro-7 was the entry-level group, and performed quite well as described in the article, though the article's comparison with (albeit similarly painted) Ultegra is kind of ridiculous imo.
The Xenon derailer design was taken directly from the similar Synchro-7 Athena gruppo, and featured Campagnolo's very first slanted parallelogram, but in a style not so reminiscent of other's such designs (the dropped B-knuckle not featured, just the slightest bit of offset in a different direction giving Athena and Xenon rear derailers a unique look.

In today's world, good luck finding the particular Regina 7s freewheel or chain that this (and Similar Athena's) indexing was designed around.

I tried a 7s Sunrace 13-25t freewheel having HG style cogs and Shimano's 7s spacing, and had difficulty adjusting it to index accurately/silently using modern 8s chain, even after experimenting with different B-pivot positions.

But then I discovered that a narrower Shimano 9s chain immediately and completely mitigated any symptom of the slight indexing mis-match, so my Torelli with Xenon shifts really well now.

Indeed, I was struggling to imagine how it would handle with a 75-degree HT angle and 5.5cm of fork rake, which nearly puts it into negative trail territory(?).

Lively, to be sure, but perhaps with the added rake boosting the front-center dimension and allowing a shorter top tube, a way-long stem extension might weight the front wheel enough to calm the steering(?).
It had to have been rideable, sign me up!

...if I can ride one, anyone can ride one. But good luck getting anything wider than a 700x25 tire on there.
