I like the idea of super wide outer width (e.g. 36mm) but is it safe to mount 28mm tire? Isn't the sole purpose of making wheels this wide is for 35mm gravel tires to sit flush with the rim for aero benefit? Looks like they are targetting road discipline, 48mm deep on 28mm tire

I think Reynolds ATR 700 at 32mm wide is a better choice for road discipline https://reynoldscycling.com/collections ... ts/atr-700
"The wheels use a unique low-density filler to create the extra width around the bead for a smooth transition to the tire without much weight penalty. From the side it looks similar to something you might have seen as a different brake surface material, although these are disc brake only. No word on an official name, weight, or pricing on these yet. But we are told that they will be finalized in the coming months and ready for order before the end of 2018."
