I don't mind you reviving this thread as I am considering a pair of Decadence when moving my current sturdy but heavy Aeolus 35 over to the bike I am getting for my partner to replace her stock alu wheels. This would be tubeless not tubulars. The reviews out there are overwhelmingly positive but usually for clinchers/tubeless. I am also in Australia so prices compare even better than for you overseas people since we always pay a premium on anything coming in. That said, I am not too price sensitive if there are reasons to avoid.
Also, does anyone have anything to say about the decadence hubs that come with these wheels, I think they are 48 engagement. I can't find much about them.
