Better braking, especially in wet conditions, is one of the premium features on all Zipp NSW rim-brake wheels. Zipp’s Showstopper™ brake track technology:
- includes 317 groves on each side of the wheel that are directional to wheel rotation to increase stopping power and help clear away water from the braking surface.
- delivers equal braking force in wet conditions when compared to industry leading aluminum rims.
- is optimized for use with Zipp Tangente Platinum Pro Evo Brake Pads.
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, we have introduced a molded-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.
The net result is equal braking force in wet conditions when compared to industry leading aluminum rims. Showstopper technology delivers greater stopping power in wet conditions than any carbon wheel ever produced.
