Причин по которым можно загнать переклюк в колесо очень много. При этом не обязательно ломать спицы. Колесо у него было на месте на момент поломки: Absalon_1.jpg "If you go to 1 hour 42min on the Redbull video there's a slow mo shot of where Julien Absalon's bike broke. He appeared to be just riding along beforehand. The rear derailleur looks to have broken but the bike was still intact.

The rear wheel came out of the frame when he threw it down a slope in anger shortly afterwards. After the throw the frame is clearly broken as the entire rear derailleur is detached as he drags it away." (с)
