Available in the \u003cstrong\u003eSRAM XDR cassette body\u003c\/strong\u003e configuration with a 12x142mm thru-axle and Center-Lock disc interface, this rear wheel is purpose-built for riders who want measurable aero and compliance benefits from their wheels, not just a weight number on a spec sheet.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"3:1-3:538;495-1032\"\u003eThe extra rim width changes how a gravel tire behaves under pressure. Running a compatible tubeless tire at lower PSI on a 32mm-wide rim produces a larger contact patch without the sidewall squirm you'd get on a narrower rim — that translates directly to better grip in loose corners, more traction on loose climbs, and reduced hand fatigue over long days in the saddle. The 54mm rim depth creates a smooth aerodynamic transition with wider gravel tires, where a shallower rim would leave an aerodynamic gap between tire and rim profile.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\" data-sourcepos=\"5:1-5:22;1034-1055\"\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\" data-sourcepos=\"7:1-10:135;1057-1535\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" data-sourcepos=\"7:1-7:111;1057-1167\"\u003eGravel riders running \u003cstrong\u003eSRAM AXS or any SRAM XDR-compatible drivetrain\u003c\/strong\u003e who want a meaningful wheel upgrade\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" data-sourcepos=\"8:1-8:127;1168-1294\"\u003eRiders doing mixed-surface riding — pavement to gravel transitions — where aero efficiency and vibration damping both matter\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" data-sourcepos=\"9:1-9:106;1295-1400\"\u003eCyclists who want carbon rims and tubeless performance without paying for Zipp's top-tier XPLR wheelset\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" data-sourcepos=\"10:1-10:135;1401-1535\"\u003eRiders who prioritize durability and serviceability (replaceable pawl-spring hub, stainless cartridge bearings) on technical terrain\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"12:1-12:100;1537-1636\"\u003eConsider a different wheel if you're running Shimano or SRAM HG cassettes — this wheel is XDR-only.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\" data-sourcepos=\"14:1-14:26;1638-1663\"\u003e\u003cstrong\u003eWhat to Look For\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\" data-sourcepos=\"16:1-18:107;1665-2141\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" data-sourcepos=\"16:1-16:212;1665-1876\"\u003e\n\u003cstrong\u003eTire compatibility\u003c\/strong\u003e: This rim uses hookless construction.

On gravel-specific tires, the 303 XPLR S rim profile reduces the aerodynamic penalty of running wider rubber rather than treating width as a trade-off.
