Well yeah, but... I've never seen proof. They say "stiff enough for Di2!", whatever that means. What's the stiffness requirement for Di2? The shop manager told me the aero ones are stiffer too. How's he know? Nothing's published. It's tempting to assume that solid rings are stronger, but that's not obviously true (and alloys make a ton of difference). So who knows?
But they look awesome, so yeah, I went with them.
