Its 40 mm rim, 25 mm internal width and integrated AXS Wheel Sensor make it a useful starting point for riders who want to plan around wider road tires and monitor pressure, rather than simply choose the deepest rim.\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.

Follow Zipp's AXS Wheel Sensor setup instructions, including its sealant-injector procedure.

It may include a rough lane, an old bridge, a long climb or a stretch that makes you reconsider yesterday's tire pressure. For that rider, the buying question is not only how a wheel looks on an aero bike. It is whether the whole setup makes sense for the roads you keep choosing.\u003c\/p\u003e\n\u003cp\u003eThe 40 mm rim and 25 mm internal width are designed for a wider road-tire platform, with Zipp optimizing the profile around 30-35 mm tires. The AXS Wheel Sensor adds another dimension: on-bike pressure monitoring helps you check your setup and notice changes during a ride. ZR1 hubs with stainless-steel bearings complete a package that brings aero design, tire volume and pressure awareness into the same all-road conversation.\u003c\/p\u003e\n\u003csection aria-label=\"Zipp 303 SW product views\" class=\"brimstone-zipp-visuals\" style=\"margin:28px 0;\"\u003e\n\u003ch3\u003eZipp 303 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 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-sw-a1\/productassets_wh-303-sw-a1_fg\/wh-303-sw-tl-dbcl-700f-12x100-std-b1-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;\"\u003eA 40 mm profile for the all-road build.\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 SW rear wheel, angled view with XDR freehub and AXS sensor\" decoding=\"async\" height=\"1000\" loading=\"lazy\" src=\"https:\/\/www.sram.com\/globalassets\/image-hierarchy\/sram-product-root-images\/wheels\/wheels\/wh-303-sw-a1\/productassets_wh-303-sw-a1_fg\/wh-303-sw-tl-dbcl-700r-xdr-12x142-std-b1-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;\"\u003eThe rear wheel, XDR driver and integrated AXS sensor.\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.
