@toxin Peter showed me a picture of the 20h hub. It's 294g/set and slotted straight pull, not side entry.
The updated wheels will be nice when they are released. The only drawback I see is that, according to many manufacturers' charts, 26mm internal width needs a wider road tire than most people would want to run. I think I would feel comfortable with 32mm on those wheels, following the rough ETRTO guidance, but that's at odds with the charts from Conti and Schwalbe.
A touch on the heavy side but ok.
Yeah, not great for the front, personally I'd only be running these rims on the rear anyway
