Technology: 

Hexfin Aerodynamic Boundary Layer Control (ABLC):The Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. 

Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim profile to further reduce high yaw drag and improve crosswind stability. Carbon Clincher: Two years of intensive prototyping and testing has resulted in a clincher that utilises elements of motorsports brake systems to maximise heat management. Their investment has paid off in spades, with all Zipp Carbon Clinchers now passing the rigorous safety standards of CEN. 

Visco-Elastic Constrained Layer Control (VCLC):Using a vibration absorbing material that is compressed between layers of solid carbon laminate on the rim surface. This technology means that when the rim received an impact from the road, a lot of the shock is absorbed by the VCLC system, resulting in a 10% reduction in road vibration. 

Showstopper: Showstopper is a complimenting pairing of a directional, moulded-in, texture with silicon carbide particles suspended in the surface resin. The current media blast process applied to all Zipp rims increases the surface roughness of the brake track providing the rider with consistent and responsive braking. 

In order to improve this for the wettest of rides, Zipp has introduced a moulded-in groove specifically tuned for the Zipp Tangente Platinum Pro EVO Brake Pad. The grooves have been optimized to interact with leading edge (relative to the rotation of the wheel) of the brake pad and the four cooling channels. 

The leading edge of the pad and first two channels efficiently wipe water and debris outward, cleaning and drying the braking surface, while the second two cooling channels have maximum interference with the grooves allowing greater braking force than a smooth rim. 

The cleaning effects of the groove and pad interaction improve brake feel and consistency even in dry conditions.
