ZIPP 404 Firecrest Carbon Wheelset Clincher
Wheels with 58 mm high rim profile has a long tradition in the arsenal of Zipp wheels. Since the early 90's races are won on Zipp wheels this height. And now more than ever. Since the introduction of Zipp Firecrest Profile Zipp could significantly improve the 404 wheelset in all areas.
With a maximum width of 26.5 millimeters, the wheels have become significantly wider compared to their predecessors. 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 Firecrest wheelsets easily handled even in cross winds. To save every watt of pedaling in the fight against the wind, and the 404 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 set 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, is not dangerous for the rims.
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 terrain 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 thinner in 2014 in order to adapt better to the dimple design can and it could also be a few grams of weight can be saved.
