This is the WH-303-XPS-B1 generation. Consider it when your shopping list is centered on dedicated gravel wheels and suitable wide tires, not a narrow road setup with occasional unpaved detours.\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.

Zipp support recommends 40-60 mm; approval and measured frame clearance are still required. The wheel pressure ceiling is 50 psi \/ 3.45 bar, with lower applicable tire limits taking precedence.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHookless setup:\u003c\/strong\u003e 3.45 bar \/ 50 psi wheel ceiling.

This is where a gravel-specific wheel starts to make sense. The 303 XPLR S puts its wide rim at the center of the build, inviting you to think about tire support, surface changes and the long route ahead as parts of the same ride.\u003c\/p\u003e\n\u003cp\u003eZipp's Total System Efficiency approach looks beyond air resistance to rolling and vibration losses. On the XPLR platform, the wide rim is designed around approved gravel tires and lower-pressure setups that support traction and absorb rough-surface vibration. The S pairs that gravel-specific concept with 76\/176 hubs. The result is a distinct alternative to starting with a road wheel and simply fitting a larger tire.\u003c\/p\u003e\n\u003csection aria-label=\"Zipp 303 XPLR S product views\" class=\"brimstone-zipp-visuals\" style=\"margin:28px 0;\"\u003e\n\u003ch3\u003eZipp 303 XPLR S: 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 S 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-s-b1\/productassets_wh-303-xps-b1_fg\/wh-303-xp-s-cl-f-12x100-dgry-b1-dside-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 wide-rim XPLR platform, viewed from the front.\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 S 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-s-b1\/productassets_wh-303-xps-b1_fg\/wh-303-xp-s-cl-r-xdr-12x142-dgry-b1-3q-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;\"\u003eThe rear-wheel construction and driver, shown from an angle.\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.
