I have a volare 20, with Veloce and Zonda wheels. not quite the 853 frame tubing but next tier down.
I find it really comfy, its nicely made, just watch the cable barrel adjusters on the headtube as mine snapped easy, simple to replace though.
plenty stiff enough for me and i’m 90+kg and can churn out quite a bit of power, i.e i don’t notice any flex where as i can normally twist a frame quite easily.
As i said, despite being stiff its plenty comfy for long distance, not as comfy as some more distance oriented frames, but for its type, its not half bad.
Plus, they look awesome!
