An integrated sensor in the Zipp rims measures the air pressure and displays it via LED and on the bike computer display. The 303 SW are very wide. They are aerodynamically top, robust, but also quite heavy. The hookless rims also require compatible tires and a maximum permissible air pressure of five bar.
