ZIPP 404 Firecrest Carbon Clincher Front
Wheels with 58 mm high rim profile has a long tradition in the arsenal of Zipp wheels. Since the early 90s, races are won on Zipp wheels of this height. And now more than ever. Since the introduction of zips Firecrest Profile Zipp could significantly improve the 404 wheelset in all areas.
With a maximum width of 26.5 millimeters, the rim has 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. 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 404 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.
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.
