Could you take closer pics of the hubs?

@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

If you wanna some reference: I went with t800, d50cu33, inhouse hubs, cxray and brass nips - 1420g.

I've been using 28mm PowerCups on 24mm internal rims and while the tyre casing is wide (meaning the tyre blows out to about 31.5mm) the tread width definitely isn't. I can see from the scuffing that I have been riding on the sidewall quite a bit. I wouldn't recommend those tyres for rims that wide, and probably only for 21-23mm internal width.

oh well..
.... the tires have arrived. mine's the clincher ver.
worse comes to worst, i'll just put on my rears, on both future d50cu-33 n my parcours chrono, since they seems have better puncture protection that gp5k clinchers

Yeah, I don't really understand why many (?) people here are going for those 26 mm inner width rims for road use with narrow tires. ETRTO recommendations don't exist for nothing. You can usually go a bit further than recommended, but it's a bit of a gamble.

Unless you want to to exclusively run 32+ mm tires, don't get those rims!

That said, it would be great to see something between 21 mm and 26 mm rim width. Something like 23 or 24 mm would be pretty versatile.

I'm running the 50x26 IW Carbonspeed wheels with  38c Schwalbe Pro One tires and the ride quality is incredible.

Finally got my hands on the wheelset and so far I'm happy with it. 65mm rim with 26mm internal with in-house hubs and pillar 1420 spokes weight just under 1500g. The paintless finish looks fantastic. 30mm Schwalbe Pro one measures around 33mm and sits flush with the rim

What frame are you running these on?  What’s your max clearance? 

I want to run 32mm tires on a new frame with a max clearance of 32mm.  Wondering something like the 26mm IW/33mm EW is pushing it a bit far unless I get something like the LT 301D.

32C clearance, or 32mm? There's no standard. Sometimes a seller will start saying 30C, then start saying 32C instead because it's what clients want to hear. My lt268 has plenty of clearance for 34mm, or more. Velobuild 177 claims to clear 32C but various users showed that it doesn't.
Best is to ask the factory for the CAD drawing and how much space there is between seat stays. That's what long teng sent me when I inquired before ordering my lt268.
In theory, 32C clearance should allow you to run 32C with a 33mm rim. For aero purposes, I'd suggest 30C on 33mm rim though, as the 30C will measure wider than 30 on a 33 rim.
Fast on the flat. And nowhere else.
