From the 2022 season onwards, the number of riders in each  UCI Women’s WorldTeam may not be fewer than 10. 2.13.167 If the number of riders proves to be less than the stipulated minimum, the UCI shall issue  a warning to the UCI Women’s WorldTeam and allow it a grace period of 30 days to  rectify the situation. In case of failure to do so, the UCI Women’s WorldTeam shall be  liable for a fine of between CHF 2,000 and 20,000. To determine the fine, the UCI shall  take account in particular of the reduction of the payroll costs from which the team  benefits during the period for which its numbers fall short of the required minimum.  Riders  For the 2020 and 2021 seasons, the maximum number of riders per UCI Women’s  WorldTeam is restricted to 16. From the 2022 season onwards, the maximum number of  riders per UCI Women’s WorldTeam is restricted to 20.
