Zipp built it around a \u003cstrong\u003e32mm internal rim width\u003c\/strong\u003e and a 54mm-deep symmetrical profile. Zipp did not start from a road rim and widen it. It applied its Total System Efficiency approach to gravel, so the rim and tire are designed as one system that handles rolling resistance, vibration and aerodynamics together on rough surfaces.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe wide internal profile adds tire air volume, which lets riders run \u003cstrong\u003epressures under 30psi without tire squirm\u003c\/strong\u003e. Lower pressure lets the tire soak up surface vibration while keeping grip in corners and traction on climbs. The rim laces to Zipp's \u003cstrong\u003eZR1 Disc hub with 66 points of engagement\u003c\/strong\u003e, uses a Center Lock rotor interface and carries a lifetime warranty. Note that this wheel works \u003cstrong\u003eonly with Zipp-approved tires\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\"\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cp\u003eGravel racers and long-distance gravel riders running \u003cstrong\u003e40–61c tubeless tires\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRiders who already use, or plan to use, Zipp-approved tires.

The straight-side (TSS) bead wall gives tires a wide, supported base at low pressure. It is also why tire compatibility is restricted and pressure is capped at \u003cstrong\u003e50psi \/ 3.45 bar\u003c\/strong\u003e. Zipp shaped the deep symmetrical profile to blend smoothly into the tire's sidewall for better aerodynamic efficiency on gravel.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eHub:\u003c\/strong\u003e The \u003cstrong\u003eZR1 Disc hub\u003c\/strong\u003e is engineered in Germany.
