There have been several generations of Prince. Is it full carbon?
Generally, I don’t think that Pinarello have changed their race frame geometry much over the last few years. My impression, having ridden a few, but not the most recent ones, is that they are good handling, agile frames. I wouldn’t expect it to be any more “ harsh” than any other race frame, from any other manufacturer.
If it’s in your shop then at least it’s not a fake - there are a lot about. Keep all the documentation, if you decide to sell it on at some point that will be highly useful.
