All the components of the bicycle must be available commercially (i.e. available on the market or sold directly by the manufacturer) at the latest nine months after their first use in competition. To implement this nine-month period, the manufacturer must publicly announce that the product in question is being used in competition and when it will be available for sale. In all cases the product must be a finished product in the condition that it will be marketed. The testing of a prototype in competition is prohibited.
How does this work? If a product used in competition does not wind up becoming available within nine months of use in competition, is the rider retroactively disqualified? If Rider A on Team X uses equipment which does not become available within nine months, and helps rider B on Team X win the race, but Rider B is not using such equipment, then is Rider A retroactively disqualified, while Rider B's results, obtained with the assistance of a retroactively disqualified rider, are allowed to stand?
