Ya sure the front hub bearings aren't 30x17x7mm?? Those are 6903..

That’s exactly my point, sadly. These are non-standard bearings.

Industry 9 refer to them as 18307 bearings, but even that is non-standard bearing nomenclature.

10-4..proprietary bearings in bike 'stuff'-> dumb.."hello design engineers..start with bearing size"...what could possibly be the advantage of a 1mm larger ID..

Advantage is that smaller bearings wear out faster, sell more proprietary bearings that way.

Especially given that SRAM have pronounced that the smaller 28.99mm (!) inner diameter of their DUB bottom brackets is superior to the 30mm inner diameter of others.

What a surprise. I remember sram saying their RTC(ReturnTo Center) bar ends for tri bars were 'more aero' too...
