It is the premium aero-road choice to investigate when your decision has moved beyond whether to buy carbon wheels and toward which complete specification fits your build.\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.

The wheels help define the finished build, from the way it looks at the start line to the tire setup you take onto open roads. The 454 NSW brings Zipp's distinctive Sawtooth shape and current premium hub platform to that decision. It is a wheelset for the rider who wants the engineering to be as considered as the rest of the bike.\u003c\/p\u003e\n\u003cp\u003eThe variable 53\/58 mm profile combines Hyperfoil nodes and HexFin ABLC dimples as part of Zipp's work on aerodynamic efficiency and crosswind stability. Total System Efficiency broadens the brief to rolling resistance and vibration losses, making tire choice part of the performance story. This C1 model pairs that rim concept with ZR1 SL hubs, hybrid ceramic bearings and 66 engagement points.\u003c\/p\u003e\n\u003csection aria-label=\"Zipp 454 NSW product views\" class=\"brimstone-zipp-visuals\" style=\"margin:28px 0;\"\u003e\n\u003ch3\u003eZipp 454 NSW: 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 454 NSW front wheel, side view of Sawtooth rim\" decoding=\"async\" height=\"1000\" loading=\"lazy\" src=\"https:\/\/www.sram.com\/globalassets\/image-hierarchy\/sram-product-root-images\/wheels\/wheels\/wh-454-nsw-tl-discbrake-c1\/productassets_wh-454-ntld-c1_fg\/wh-454-nsw-tl-dbcl-700f-12x100-std-c1-c-ds-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 variable-depth Sawtooth profile 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 454 NSW 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-454-nsw-tl-discbrake-c1\/productassets_wh-454-ntld-c1_fg\/wh-454-nsw-tldbcl-700r-xdr-12x142-std-c1-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 C1 rear wheel and ZR1 SL hub platform.\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.
