announced that all non-double triangle frames would be illegal for road racing starting in January 2000. This led Zipp to discontinue production at the end of 1997. The existing component inventory was sold to one of the men who had worked on frame production, and the frames have not been produced since then.

Current Status

Since January 2000, Zipps have not been legal for use in road racing, or UCI-organized time trials. They are, however, legal in triathlons, which have much more liberal equipment rules. While they are known for being flexible and, therefore, not well suited to hill climbing, they are well suited to flatter courses.
