ZIPP wheelset 303 NSW Carbon Clincher
Making the most aerodynamic and seitenwindstabilste rim profile even better? Before this task, the Zipp engineers were when they tried to develop on the basis of outstanding Firecrest rim profile even more efficient impeller. With the NSW impellers succeeded in every way to bring the Firecrest series to the next level. The 303 wheelset is the perfect all-rounder among NSW impellers. Easy enough for the high mountains, aerodynamic enough for long solo rides in wind and sturdy enough for the cobblestones and the training routine.
In the development of Cognition hub was a target in the first place: Maximum speed! This was achieved in several ways. Firstly, specifically adapted to the hub Swiss ball bearings are installed, the guarantee in addition to their enormous durability lowest bearing resistance. Secondly, the Axial Clutch freewheel mechanism for an extremely low resistance makes the rolling process. It is achieved by the use of magnets instead of springs which press the lock washers to today. Internal tests have shown that the Cognition hub through this system have only half of resistance to the top ratchet freewheels on the market. The 36 grid points of the toothed discs also provide a very direct response when comes back pressure on the pedal. For maximum translation span or a 1-way drive the Cognition hub can also be equipped with an XD freewheel body.
Showstopper braking surfaces
Among the carbon rims include the braking characteristics of the Firecrest rims of the best on the market. But that was the engineers of Zipp still not good enough. The newly developed Showstopper braking surfaces contain silicon carbide. This material is harder than steel and provides a uniform braking power at very high levels. Yet this, it is extremely abrasion resistant and the outstanding features of the brake surfaces thus remain over the entire life of the rim obtained. The wet braking properties to improve the water and dirt during braking has been incorporated into the brake surfaces of a structure, transported faster. In dry conditions the grooves of the heat dissipation, thus improving braking performance on long runs make.
ABLC Sawtooth Technology
The rim of the NSW wheelsets equips Zipp from his proven ABLC Dimple Design. This helps, as in the surface of a golf ball, for directing the air flow efficiently over the rim. Another new feature is the arrangement of dimples in 12 blocks whose compartments are connected by a sawtooth profile. By this arrangement, the air resistance of the wheels could be further reduced and the positive effect sets in NSW rim a even at speeds above 30 km / h.
With Impress technology, the images are printed directly on the impeller. This saves weight and helps ABLC Dimpledesign while fulfilling its mission - to eliminate air turbulence.
