It is the premium XPLR option in this Brimstone selection for riders considering a gravel-race build around approved wide tires, rather than adapting a road wheel to every surface.\u003c\/p\u003e\n\u003cdiv style=\"padding:16px 18px;background:#f4f7f4;border-left:3px solid #0F502C;margin:20px 0;\"\u003e\n\u003cp\u003e\u003cstrong\u003eWhat you are buying:\u003c\/strong\u003e A complete front-and-rear wheelset.

Open straights reward an aero-minded setup; loose corners, rough tracks and long climbs ask different questions. The 303 XPLR SW approaches that changing course as a complete wheel-and-tire problem. It is a compelling direction for the rider building a dedicated gravel-race bike rather than asking a road wheelset to cover every role.\u003c\/p\u003e\n\u003cp\u003eThe 32 mm internal rim is designed to work with approved gravel tires, increasing air volume and supporting lower-pressure setups. Zipp's aim is to reduce the energy lost to rough-surface vibration while retaining tire support and grip. The deep, wide profile also addresses the transition between tire and rim for gravel aerodynamics. ZR1 DB hubs with 66 engagement points distinguish the SW equipment package from the S.\u003c\/p\u003e\n\u003csection aria-label=\"Zipp 303 XPLR SW product views\" class=\"brimstone-zipp-visuals\" style=\"margin:28px 0;\"\u003e\n\u003ch3\u003eZipp 303 XPLR SW: a closer look\u003c\/h3\u003e\n\u003cdiv style=\"display:flex;flex-wrap:wrap;gap:16px;align-items:stretch;\"\u003e\n\u003cfigure style=\"margin:0;flex:1 1 260px;min-width:0;background:#ffffff;border:1px solid #e5e9e5;border-radius:8px;overflow:hidden;\"\u003e\n\u003cimg alt=\"Zipp 303 XPLR SW front wheel, side view\" decoding=\"async\" height=\"1000\" loading=\"lazy\" src=\"https:\/\/www.sram.com\/globalassets\/image-hierarchy\/sram-product-root-images\/wheels\/wheels\/wh-303-xplr-sw-a1\/productassets_wh-303-xpsw-a1_fg\/wh-303-xpsw-dbcl-700f-12x100-std-a1-c-side-s.png?w=1000\" style=\"display:block;width:100%;height:auto;max-width:100%;object-fit:contain;background:#ffffff;\" width=\"1000\"\u003e\n\u003cfigcaption style=\"padding:12px 16px 16px;font-size:0.92em;line-height:1.5;\"\u003eThe dedicated gravel rim in side view.\u003c\/figcaption\u003e\n\u003c\/figure\u003e\u003cfigure style=\"margin:0;flex:1 1 260px;min-width:0;background:#ffffff;border:1px solid #e5e9e5;border-radius:8px;overflow:hidden;\"\u003e\n\u003cimg alt=\"Zipp 303 XPLR SW rear wheel, angled view with XDR freehub\" decoding=\"async\" height=\"1000\" loading=\"lazy\" src=\"https:\/\/www.sram.com\/globalassets\/image-hierarchy\/sram-product-root-images\/wheels\/wheels\/wh-303-xplr-sw-a1\/productassets_wh-303-xpsw-a1_fg\/wh-303-xpsw-dbcl-700r-xdr-12x142-std-a1-c-3q-s.png?w=1000\" style=\"display:block;width:100%;height:auto;max-width:100%;object-fit:contain;background:#ffffff;\" width=\"1000\"\u003e\n\u003cfigcaption style=\"padding:12px 16px 16px;font-size:0.92em;line-height:1.5;\"\u003eAn angled view of the rear wheel and XDR driver.\u003c\/figcaption\u003e\n\u003c\/figure\u003e\n\u003c\/div\u003e\n\u003cp style=\"font-size:0.86em;line-height:1.5;color:#555;margin:10px 0 0;\"\u003eOfficial Zipp product photography.
