With TSE, the 858 NSW Carbon Tubeless Disc-brake wheelset features a tubeless and hookless rim profile for seamless tire interface and huge drop in weight. The 858 gives you the benefits of our deep rims at weight typically associated with rims that are 20mm shallower. The wheel’s internal width is 23mm, ideal for running wider tires with lower pressures for decreased rolling resistance. That’s how TSE technology helps you conquer the four barriers to speed: Wind Resistance, Gravity, Rolling Resistance, and Vibration Losses.\u003c\/p\u003e\n\u003cp\u003e The 858 NSW’s undulating 82mm-85mm deep rim shape, our patented Sawtooth profile, is our highest performing design for aero efficiency and crosswind stability. The result is the pure speed, especially for triathletes, time trial specialist, and any other speed freak. What’s more, while this wheelset is optimized for tubeless tires, you still have the option to run tubeless ready tires with tubes.\u003c\/p\u003e\n\u003cp\u003eThe 858 NSW is fastest with a 28mm tire. In triathlon, running wider tubeless tires at lower pressure makes you faster while also smoothing out the ride so your body is fresher for the run. Disc brakes also offer more reliable speed modulation and braking power in all weather conditions. The 858 NSW features the premium ZR1 SL hubset with ceramic bearings and 66 points of engagement.\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"*:tw-text-slate-950\"\u003eZipp’s 404 Firecrest Tubeless Disc brake is a pro-proven Speed Weapon for any situation. The 404’s heritage as Zipp’s icon of speed extends back decades, and its future is even brighter. At 58mm deep, the 404 Firecrest Tubeless is ideal for road races, time trial and triathlon, gran fondos, and riding over varied terrain. The wheelset’s 23mm internal width is perfect for running wider tubeless tires at reduced air pressure. That is a vital component of Total System Efficiency™, or TSE™, an approach to speed on ever-changing roads and riding conditions. Specifically, TSE™ focuses on overcoming specific barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses. Zipp’s ABLC™ Sawtooth™ Technology uses an intricate dimpling pattern to improve aero efficiency. Zipp’s use of hookless (straight side) rims in the 404 Firecrest is integral to Making You Faster. With hookless, the transition between the tire and the rim is more seamless and aero. Zipp’s hookless rims have more efficient resin distribution, which means lighter, stronger wheels. At the center of the 404 Firecrest Tubeless Disc-brake is a versatile and durable new hubset, the German-engineered ZR1 DB. If you had to choose just one wheel for road riding and racing, the 404 Firecrest Tubeless Disc brake is a savvy and speedy choice.\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan class=\"*:tw-text-slate-950\"\u003e\u003cstrong\u003eMax tire pressure: \u003c\/strong\u003e73psi\u003cstrong\u003e\u003cbr\u003eMax recommended rider weight: \u003c\/strong\u003e115KG\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan class=\"*:tw-text-slate-950\"\u003e\u003cstrong\u003eRim depth: \u003c\/strong\u003e80mm Rear\/58mm Front\u003cstrong\u003e\u003cbr\u003eRim - \u003c\/strong\u003einside width: 23mm\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp class=\"product-detail-overview-description-text\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Zipp","offers":[{"title":"Zipp 858\/454 NSW Combo Wheelset","offer_id":56340357775684,"sku":null,"price":3899.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0180\/4447\/files\/Screenshot_2026-01-30_at_17-42-54_858_NSW_Tubeless_Disc-brake_WH-858-NTLD-C1_SRAM.png?v=1770993185","url":"https:\/\/shop.base2race.ie\/products\/zipp-858-454-nsw-combo-wheelset","provider":"Base2Race","version":"1.0","type":"link"}
