Zipp 404 Firecrest Carbon Road Wheelset – Clincher

Material: [rim] carbon fiber
Rim Width: [brake track width] 24.73 mm, [maximum width] 26.53 mm
Rim Depth: 58 mm

Irrespective of if you are tearing Kona to pieces or bridging the distance to the breakaway, Zipp’s 404 Firecrest Carbon Clincher Road Wheelset will heighten your most sensible end, and deliver an unparalleled versatility in ride quality. And for the contemporary iteration of the 404, Zipp’s refined 188/V9 rear hub and more efficient spoke lacing pattern have been employed. The 404 is one Zipp’s such a lot ambitious rim shapes. Designed to bridge the distance between tubulars and clinchers, the 404 Firecrest maintains a rim depth of 58mm and an aerodynamic brake track width of 24. 73mm. 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 it provides greater vertical and lateral compliance with increased Keep watch over, comfort, and rigidity. Even as the 404 advantages from these welcomed additions, to succeed in the Zipp-usual of strength and rigidity, the 404 utilizes unidirectional fibers to deal with the tensile and comprehensive loading throughout the rim, and woven fibers within the spoke-hole areas. A woven silica-ceramic fabric and a woven carbon fabric encapsulate the braking and tire-mounting surfaces. The combo of fiber patterns creates a high stiffness-to-weight ratio without stacking up the grams. Various Zipp technologies went into making the 404 the one of the vital versatile wheels within the Zipp arsenal. First, the dimpled full-carbon hoop acts as a leaf spring for road vibration and affect, Even as the dimples of the Aerodynamic Boundary Layer Keep watch over (ABLC) at the curved rim section work to create a slight turbulence right away above the rim surface. This creates a synthetic boundary layer that forces the laminar boundary layer towards the forward a part of the rim to transform turbulent. This process enables airflow to stay connected over more of the rim for an extended time frame, providing a lower level of integrated drag. The drag that ABLC creates is referred to as …
