>>1866938>A head tube, beacuse of its simple shape, will generate less turbulance than the complex shape of a rim brake. A box has a "simple" shape too but isn't aero.
>A rotor would generate less turbulance than a rim brake.<-- See those channels that catch air while it spins to cool it off so it doesn't melt? That's pretty much the opposite of 'aero'. Rim brakes don't have that.
>Lol, hambini.Post your aerodynamics phd then.
>Having a flat brake track makes achieving that more difficultIf your tire width and rim width match then the side of your tire is flat. If they don't match then you're fucked anyway.
>Ignoring the age of the video, one of the racers is running Sram Red AXS and their bike weighs 6.83. So what point are you trying to make?Could've been 6.7 without disc brakes.
