The Zipp 808 Firecrest Carbon Clincher the Zipp engineers have not just adapted only the technology of the proven 404 carbon clinchers on a 82 mm rim profile, but matched in many hours in the wind tunnel and various prototype models perfectly adapted to the rim height of the 808th Out came the fastest high profile carbon wheel is the ever tested.
With a maximum width of 27.5 millimeters, the wheels have become much wider 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. Yet to experience a wider tire better support what cornering grip improved. By bulbous Firecrest rim shape the rim width of the braking surface to the spoke holes remains approximately constant. With this form, it succeeded the Zipp engineers that the wind resistance between the windward and leeward side of the rim or less balanced. This makes the wheelset easily handled even in cross winds. 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 guided by micro turbulence airflow 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.
Carbon wheels are not known for their outstanding braking performance and good dosing of the brakes. With the Carbon Clincher Technolgie Zipp could improve this vulnerability enormous. A special carbon matrix at the brake surfaces, the rim has a braking performance which is almost at the level of an aluminum rim. Also make high brake temperatures, as may occur during long downhill stretches, presents no danger to the rim.
Spoked is the wheelset with front 18 and rear 24 Sapim CX Sprint spokes Straightpull to Zipp 77/177 hub pair. This makes its optimized flange geometry for high rigidity and durability of the wheels. Furthermore, they offer an excellent bearing sealing and adjusting the bearing clearance is no longer necessary. For all the wider translation for use in extreme intended use prefer to an XD Freilaukörper for retrofitting is available.
That Zipp continually optimizes all details of their wheelsets, is also reflected in the revised rim stickers. These have become even thinner in order to adapt better to the dimple design can and it could also be a few grams of weight can be saved. They are available in the colors matt white and matt black
