What happens when Zipp's fastest wheel gets faster We're talking drastically faster, here. Well, it gets picked up by nearly every pro squad known to man, it stacks the starting line at Kona, and it slays the World's time trial by around five seconds. We're not kidding. For 2013, the Zipp 808 Firecrest Carbon Tubular is faster than the 2012 by around 15 seconds over 40 kilometers. Zipp made it a touch deeper, a tad wider, and far quicker. Riding is believing. The Firecrest 808 is Zipp's most ambitious rim shape to date. Designed to control airflow, the 808 Firecrest carbon tubulars maintain a deeper, 82. 0mm rim depth and a wider, 27. 5mm maximum width. Using computational fluid dynamics, Zipp moved the center of pressure towards the steering axis to create the most stable and predictable deep-section rim on the planet. Zipp found that a wider rim offers greater vertical/lateral compliance for increased control, comfort, and rigidity. For the strength and rigidity, the Firecrest 808 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 the highest stiffness-to-weight ratio in Zipp production. A number of Zipp technologies went into making the 808 Firecrest carbon tubular the fastest wheel 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 dire...
