Zipp’s 404 Firecrest Tubeless Disc-brake is the icon of speed with three decades of use. 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, and gran fondos. 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. Outdoor testing commissioned by Zipp revealed the real-world gains of Zipp TSE. A bike- and-rider system weighing 85kg (187lbs) on the new 404 Firecrest with 25mm tires required 286 watts to maintain a speed of 40kph. That’s a 4-watt savings compared with the previous model 404 Firecrest. At the center of the 404 Firecrest Tubeless Disc-brake is a versatile and durable 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. Technology: Total System Efficiency ABLC Dimples Features: Versatile race wheelset for the modern road race bike with tubeless and hookless rim profile Optimized tire bed for easy tire installation Wide 23mm rim profile creates a better tire interface to be fast on or off the road New ZR1 DB hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement Ships with 12mm front and rear end caps Center locking rotor interface. Lockring is included with the wheels XDR or SRAM/Shimano driver bodies Campagnolo driver body sold separately The 404 Firecrest Tubeless Disc-brake is about 370 grams lighter than its predecessor 1450g wheelset* Front 660g Rear 790g Lifetime Warranty *Lightest configuration: 12mm through axles and XDR body.

45mm Deep The 45mm deep 303 Firecrest delivers unmatched aero performance when used with the wide tires that today’s riding demands. Zipp has achieved this with a wide disc-specific rim design featuring ABLC dimples extending all the way to the outer edge of the rim. In addition to achieving AeroBalance™, the industry-leading crosswind stability and low aerodynamic drag that defines all Firecrest wheels, the new 303 Firecrest delivers lower drag than the outgoing version when used with 25c or wider tyres. The aerodynamic performance gap between a narrower rim and the new 303 grows even larger with 28c and wider tyres thanks to a smoother transition between the tyre’s profile and Zipp's new rim shape. Tubeless Rim Designed from the start as a tubeless rim, the 303 Firecrest features a rim bed made with internal ridges to lock the tyre’s bead in place, ensuring secure performance, even when ridden at lower tyre pressures. Setup tubeless and emblazoned with your choice of three colour decal options (optional extra), 303 Firecrest wheels are as alluring as they are easy to use. And should you choose to run tubed tyres, the new 303 is fully compatible. Durable Carbon Layup A new carbon fibre layup keeps weight low while maintaining the 303’s legendary durability. The rim’s lightweight design allows the 303 to glide up the steepest climbs while their robust 77D front hub, paired with 24 Sapim® CX-Ray spokes, keep the wheel stiff and responsive. To ensure compatibility with any bike, Zipp's versatile 77D hub comes with swappable end caps to work with QR’s and thru-axles, including 12x100mm and 15x100mm front thru-axles. And like all Zipp carbon wheels, the new 303 Firecrest is laid up, moulded, drilled and assembled in Indianapolis, USA. Built to take you to places you’ve never been, the 303 Firecrest® Tubeless Carbon Cincher will go the distance. It’ll just take less time. Each Wheel Includes: Zipp Tubeless valve extender and valve-core wrench Zipp rim tape (factory taped) Zipp Tangente quick-release skewer Zipp thru-axle end caps
The 297 MX platform uses a 29"" wheel at the front and a 27.5"" at the rear, giving you the perfect balance of pace, stability, agility and control for riding anywhere on Earth. This kit optimises your Giga 290 into a custom super-enduro that ensures more front-end grip, enhanced rolling efficiency and playfulness on steep descents and technical terrain sections. GLUTTONY – HABITUAL GREED OR EXCESS. As riders, we are all guilty of the gluttonous sin; we never stop striving, never stop pushing, enough is never enough in the hunt for the ultimate. It’s a constant push for bigger, longer, rougher, and faster with ever-increasing demands on the performance and capabilities of our bike. The pursuit is endless, and the result is that the Giga is now available in an all-new 297 MX platform. This Nukeproof Giga 297c MX kit includes everything you need* to convert a 290c Giga frame into a 297c MX bike, running a 29” front and 27.5” rear wheel. Why would you want to do that? A mixed wheel set-up uses a 29” wheel up front to maximise grip and rolling efficiency and replaces the 29” with a 27.5” wheel out back. The smaller 27.5” rear wheel ensures nimble handling and extra clearance for riders when leaning off the back of the bike (Especially on steep terrain). No additional frame parts are needed to install the Giga MX Kit. All current Giga 290 frame parts will transfer to the MX Kit when installing as shown in the Install Guide. Note: You will require a Boost 148mm 27.5” Rear wheel and tyre, not included. New gear cable and brake olive and barb will be required in most cases. The Nukeproof GIGA: Gluttony is not a sin.

No. We designed the Giga as a series of parts that can be fitted together to make different configurations. As a result, the geometry remains the same. For exact geometry please reference the GEO’ chart. - Can I fit this myself at home? Yes, using the linked Install Guide and you are a competent mechanic with the correct tools and the know-how for using them. Due to the complex nature of a full-suspension frame, there are a lot of moving parts that must be installed and assembled in the correct order. It is also imperative that the correct parts are greased, thread locked or torqued to specification. Failure to do so would void the warranty of the frame. If you do not have the know-how, then please contact your local Nukeproof dealer or skilled service centre.
