Um yeah, riiiight…
This isn’t a criminal case or anything but if they didn’t take the bike directly from the girl at the finish, it’s kinda open to a stupid explanation like this.
Didn’t she have a mechanical out on the course or something? Who knows how long it was before they asked to see the bike. If she really did knowingly ride a doped bike, she should’ve just packed up the van and gotten out of town before the race was even over!
