Black Inc developed it alongside the \u003cstrong\u003eFactor OSTRO VAM\u003c\/strong\u003e aero road bike. The front rim is shallower so the bike stays more stable in crosswinds and gusty conditions. The deeper rear rim adds aero depth where wind has less effect on steering. Most aero wheelsets use the same depth front and rear, so this split is the main thing that sets the 48|58 apart.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe rims measure \u003cstrong\u003e23mm internal and 29mm external\u003c\/strong\u003e and use a \u003cstrong\u003emini-bead hook\u003c\/strong\u003e profile built for \u003cstrong\u003e28mm tubeless or clincher tires\u003c\/strong\u003e.
