ZIPP 303 Firecrest Carbon Clincher Front
In recent years, the Zipp 303 wheelset has established itself as one of the most versatile wheelsets under the road professionals. Been on the Tour de France to the Pavés of Paris-Roubaix, with its light weight and its high stability in the won the toughest race in road racing 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 much wider. This ensures even at 25 mm wide tires for a virtually seamless transition from the tire to the rim flange, which improves the air resistance significantly. 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 Firecrest wheelsets even in strong crosswinds rather well. In order 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 are derived by micro-turbulence air flow with less resistance on the rim.
Carbon wheels are not exactly outstanding braking performance and good controllability of brakes known for. With the Carbon Clincher Zipp Technolgie could greatly improve this vulnerability. By a special carbon matrix at the brake surfaces, the rim has a braking rim which is almost at the level of aluminum. Also make high brake temperatures, as may occur during long downhill stretches, no danger to the rim is.
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.
