>>1166158>1/18 headtubes, tapered headtubesYes, but not really necessary. 1 1/8 headtubes are lighter with aluminum/carbon steerers, I'll give you that. Tapered headtubes have more to do with big downtubes rather than needed any headset stiffness or durability.
>fucking threadless forks themselves to begin withOddly enough, not threadless stems though.
>31.8 handlebar clampsBasically no advantage for road. Ultralight 26mm alloy handlebars were often of similar weightof modern carbon handlebars. The problem is the 31.8 is basically all at the clamp, where it doesn't actually help because the bar needs a certain thickness to resist clamping forces and the stem clamps aren't really wider. 31.8 is an advantage for flat bars because unclamped oversized taper can add stiffness between the controls and the stem clamp. Road bars taper too quickly for this to be useful.
>wider internal rim widthsNot really. They existed before, they just fell out of favor.
>larger diameter seat tubesNot an advantage. The main reason for an oversized seat tube is an oversized top tube. Oversize top tubes are no longer popular because people are over super stiff frames. Seatposts don't need to be stiffer and larger ones are often heavier and less compliant.
>shorter stemsWhat does this even have to do with road?
