Used to have some Assos Roubaix Mille bib 3/4, which were more comfortable than practically any other pair of shorts I’ve ever used – more so than my FI Unos, FI Milles and FI.13. When they eventually wore out, I was no longer working in a bike shop, so ‘slummed it’ and bought Castelli Sorpasso 3/4. I’m regretting it. They’re just not as good; I could wear the Assos all day – 3 hours in the Castellis finish my bum off.
So, in my opinion – Yes. Assos totally worth it.
