So many dumb comments by Zipp.
Let's start with this one: majority of the 250g saved are from going hookless. Measure the dimensions of the hooks on your wheels and multiply the volume by the density of carbon. Hint, your answer will be somewhere in the 10g range.
28mm will not have lower RR than 25mm unless you're pumping them to the same pressure. Which you wouldn't. At the same vertical compliance, RR is essentially the same (within BRR error margins). In any case, if you want to have 23mm inner width to allow for bigger tires, you can still meet 105 rule by making the outside width greater. Just add hooks. They'll even allow you to run 75psi with those 25mm tires without popping off.
Don't even get me started on the "smooth interface" being more aero when the tire is wider than the rim. And then unironically followed by dimples right next to the interface.
I will say though, kudos on making a 75mm+ wheel sub-1600g. That's mighty impressive. Un-kudos for the asinine price. I thought hookless was what made the 303s so much cheaper. What happened to that logic?
