You might need a microscope to understand the intricacies of the 404 Firecrest Tubular, but you certainly don't need one to grasp the magnitude of its records. From L'Alp d'Huez to Kona, it's nearly impossible to find another wheel with such a storied career. However, the best just got better with the 404's adaptation of Zipp's new 188/V9 rear hub. The future is here. The 404 is one Zipp's most ambitious rim shapes. It maintains a rim depth of 58. 0mm and a maximum width of 26. 53mm in the front and 27. 07mm in the rear. The Zipp 88/188 hubs' bearing stance has been widened by 7. 5mm, and the rim's body shape has been canted out by two percent. Zipp found that the design creates a more stable structure, and offers greater vertical and lateral compliance with increased control, comfort, and rigidity. While the 404 benefits from these welcomed additions, to achieve the Zipp-standard of strength and rigidity, the 404 utilizes unidirectional fibers to handle the tensile and comprehensive loading within the rim, and woven fibers in the spoke-hole areas. A woven silica-ceramic fabric and a woven carbon fabric encapsulate the braking and tire-mounting surfaces. The combination of fiber patterns creates a high stiffness-to-weight ratio without stacking up the grams. A number of Zipp technologies went into making the 404 Firecrest one of the most versatile wheels in the Zipp arsenal. First, the Multi-Material Co-Molding process permanently fuses a sub-200-gram aluminum hoop to a dimpled carbon structure that acts as a leaf spring for road vibration and impact. Spokes laced directly to the carbon body give you the benefit of a carbon feel and aluminum braking. Next, visco-elastic material is inserted between carbon laminate in the rim to reduce road vibration by ten percent. Lastly, the dimples of the Aerodynamic Boundary Layer Control (ABLC) on the curved rim section work to create a slight turbulence directly above the rim surface. This creates an artificial boundary l...
