>>1834684It's campagnolo
Many of the consumables are more or much more expensive and harder to find and the tools are meme tools (though still quite cheap and common enough). Atleast it's not 8 speed campag which truely has bullshit compatibility.
You're right you could over time convert away from it but campag is good stuff and it is well worth trying to service and use.
I suggest you only buy it if it actually is in good working condition. A good tell is look at the hoods. They're textured. If they're worn very smooth around the grip area it's a high mileage group, and i'd probably avoid it as a noob, unless it's very cheap.
