Did Movistar rider Ion Izagirre have a motor illegally concealed in his bike during the 16 kilometre individual time trial at the Vuelta Valenciana yesterday?
That's the question posed by Italian sports daily La Gazzetta dello Sport after footage emerged showing the rear wheel of the Spanish rider's Canyon bike continuing to spin after he crashed.
The incident comes just days after a bike prepared for Belgian under-23 cyclo-cross rider Femke Van den Driessche was discovered to have a hidden motor at the World Championships in Zolder on Saturday.
It's also reminiscent of the rumours surrounding Garmin-Sharp's Ryder Hesjedal when his rear will continued to turn following a crash in the 2014 Vuelta.
His former team mate Alex Rasmussen subsequently produced his own video showing how the wheel could keep on spinning on its own.
Spanish sports website Mundo Deportivo's take on the issue is a little different, noting that the Italian dailies didn't miss an opportunity to ignite speculation against Izagirre - accusing La Gazzetta dello Sport and others of sour grapes, in other words.
