The Zipp 404 Firecrest 12x100mm Front Wheel is engineered for speed and efficiency, adaptable to changing road conditions. With a 58mm rim depth, it's ideal for road racing, triathlons, and various terrains. The 23mm internal rim width allows for wider tires at lower pressures, enhancing performance and ride quality. SawTooth technology and its dimpling pattern improve aerodynamic efficiency, further boosted by hookless rims that reduce drag by creating a smoother rim-to-tire transition. The German-engineered ZR1 disc brake hub offers improved durability and quicker response times, ensuring the bike reacts to every movement. This wheel is a versatile race wheel for modern road race bikes, featuring a tubeless and hookless rim profile with an optimized tire bed for easy installation. The 23mm internal rim profile ensures a better tire interface for speed on and off the road. The new ZR1 DB hub is engineered in Germany with an enhanced seal design for improved durability and quicker response, featuring 66 points of engagement. It ships with 12mm front and rear end caps and has a center locking rotor interface, with the lockring included. XDR or SRAM/Shimano driver bodies are compatible (Campagnolo driver body sold separately). The 404 Firecrest Tubeless Disc brake is approximately 370 grams lighter than its predecessor, with a wheelset weight of 1450g (Front: 660g, Rear: 790g). It comes with a lifetime warranty. This is a vital component of Total System Efficiency (TSE), which addresses barriers to speed like wind resistance, gravity, rolling resistance, and vibration losses. Zipp's ABLC Sawtooth Technology uses an intricate dimpling pattern to improve aero efficiency. The use of hookless rims in the 404 Firecrest is integral to achieving faster speeds, offering a more seamless and aero transition between tire and rim, and more efficient resin distribution for lighter, stronger wheels. Outdoor testing revealed real-world gains with TSE, showing a 4-watt saving compared to the previous model 404 Firecrest for a bike and rider system weighing 85kg at 40kph. The ZR1 DB hub set is versatile and durable, making the 404 Firecrest Tubeless Disc brake a savvy and speedy choice for all road riding and racing.
