Technology:


Firecrest®
Through the pioneering use of software to analyse numerical fluid mechanics and the power of a super computer, Zipp is able to understand exactly what makes wheels go fast. Zipp then tests the most promising rim shapes in the wind tunnel and on the road. This process led to the Firecrest rim technology, which allows the airflow and centre of gravity of the wheel to be controlled more effectively, resulting in better aerodynamics, better handling in crosswinds and a better riding experience.

ABLC SawTooth™
This patented rim shape achieves what conventional aero wheels cannot: it simultaneously reduces aerodynamic drag and lateral wind forces, providing the ultimate AeroBalance™. In addition, the ABLC recesses ensure improved air flow. The result is lower aerodynamic drag and reduced lateral wind forces at any angle of attack. This is important because the steeper the wind angle, the larger the influence on the handling of the bike.

After installing the wheels I had a problem, when I lightly pressed the wheel on the side, the rotor would move to the pad and scrape against the pad. When riding standing up, and also when cornering, the rotor rubbed heavily on the pads.
I fixed it on the wheel stand after tension the spokes, the problem fully disappeared, so I give it 4 stars.
I'm an 88 kg rider and I really like these wheels now.
I use it on my all-terrain bike with tires Panaracer Gravel king Slick 35 which I installed by hand without tools. But I had to use a homemade bottle booster to get the tires to sit on the rim.
It are great on asphalt, and I almost do not notice the difference when driving on gravel, this whells are very well dampen the vibration, I like it.
