According to the UCI’s strict rules on ‘technical fraud’ it does not matter who the owner of the bike is. It is the responsibility of the rider and their team to ensure that any bike used adheres to regulations.
Yeah. The end game here is not about whether she is 'guilty' under the regs (she is), it's about whether cycling thinks, beyond reasonable doubt, she intended to use it in competition and is being dishonest.
