ZIPP 303 Firecrest Carbon Clincher Front Wheel
In recent years, the Zipp 303 wheelset has established as one of the most versatile wheel sets among road professionals. From the Tour de France to the PAVs of Paris-Roubaix, with its light weight and its high stability has won the toughest race in road racing on the 303rd
Even the 303 Zipp has upgraded his most innovative technologies: The Firecrest rim profile and the Carbon Clincher construction. The rim height of 45 millimeters has remained the same as compared to its predecessor. With a maximum width of 28.5 millimeters, the rim is however become significantly wider. This ensures even at 25 mm wide tires for a virtually seamless transition from the tire to the rim flange, which improves the aerodynamic drag significantly. 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 303 patented with zips ABLC Dimpleprofil equipped. Just like a golf ball these indentations guided by micro turbulence airflow with less resistance on the rim.
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 front wheel is radial with 18 Sapim CX Sprint spokes to Zipp's 77 hub. This makes its optimized flange geometry for high rigidity and durability of the wheel. Furthermore, it provides an excellent bearing sealing and adjusting the bearing clearance is no longer necessary.
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.
