It was way back when they released it. But campy being campy, they argued it was the same as Ultegra and charged a markup on that. Affordable for campy but its not affordable like people wanted; 105 level and pricing.
They had an issue with the BB in that they decided to switch from Power Torque to Ultra Torque. I know other users got caught up in that as it was a silent switch and it caused a great deal of confusion. I got the original PT one and haven’t had any problems. But I did have to buy a medium length Derailleur when i went 11-32 which is now the standard derailleur length for campy I believe (don’t quote me on that).
The entry group set for Campy is now Centaur 11. I have that lying around but haven’t built up a bike with it yet. Finish and feel is Alu but it has the Campy touch and is solidly built from what I see with it. Rim brake versions now go for around 500-600 which is a bit of a premium but it is coming down in price from what I see.
As for my experience with Potenza? Its a work horse and I haven’t had any issues when I went with original parts and spec. However, I tried chain waxing with non-standard chains (wipperman) and connex links and destroyed a derailleur cage because the tolerances weren’t right. Campy has a nasty habit of making everything slightly off so you can’t go after market. It is infuriating since I love to tinker.
