ZIPP 808 Firecrest Tubular Front
With the Zipp 808 Firecrest Carbon Clincher the Zipp engineers have not just adapted only the technology of the proven 404 carbon clinchers to a 82 millimeter rim profile, but matched in many hours in the wind tunnel and various prototype models perfectly to the rim height of the 808th Come out is the fastest high-profile carbon wheel that has ever been tested.
With a maximum width of 27.5 millimeters, the rim has become distinctly broadened in comparison to its predecessor. This ensures even at 25 mm wide tires for a virtually seamless transition from the tire to the rim flange, which significantly reduces air resistance. Moreover, undergoes a wider tire better support what the cornering grip improved. By the bulbous Firecrest rim shape the rim width of the braking surface to the spoke holes remains approximately constant. This form was able to Zipp engineers that the wind resistance between the windward and leeward side of the rim or less balanced. This makes the wheel even in strong crosswinds rather well. In order to save every watt of pedaling in the fight against the wind, and the 808 patented with zips ABLC Dimpleprofil equipped. Just like a golf ball these indentations are derived by micro-turbulence air flow with less resistance on the rim. This makes the wheel, even at a moderate angle of attack of 10 ° significantly faster compared to its predecessor. For more crosswind, the advantage is widening.
Spoked the front wheel is radial with 18 Sapim CX-Sprint spokes to zips 77 hub. This makes their optimized flange geometry for high rigidity and durability of the wheel. Furthermore, it provides an excellent bearing seal and adjusting the bearing clearance is no longer necessary.
Zipp that continually optimizes all details of their wheelsets, is also reflected in the revised rims stickers. These have become even thinner in order to adapt better to the dimple design and it was possible to save a few grams of weight.
