The Zipp 303 Firecrest Carbon Clincher road bike wheels have been given a new brake track. The Showstopper brake track offers more stopping power and is better dosed. That makes them even more suitable for the hills. The 77/177 hubs on the Zipp 303 Firecrest Carbon Clincher wheels have good sealing properties and durability. In short, the Zipp 303 Firecrest Carbon wheels can be used on any terrain, from flat smooth asphalt roads to hilly areas or roads with bad road surfaces.
This exclusive technique resulted in better modulation and increased stopping power. After 2 years of prototyping, extensive testing, the addition of new materials, and the adaptation of existing production processes, Showstopper braking surface can be applied. Showstopper is a coupling of an embedded texture with silicon carbide particles in the resin surface. It increases the surface roughness of the brake track, providing the rider with more consistent and responsive braking.
The ABLC SawTooth design consists of a marked dimple profile of Zipp. It ensures that airflow is conducted along the surface of the rim for optimum aerodynamics. Also, the stability is improved which provides more comfort.
