Kenny Dehaes (BEL/Lotto-Belisol) punctured halfway down the Trouée d'Arenberg / Bois de Wallers-Arenberg, which left him stranded for minutes because of trying non-campatible wheels from another team, while the Mavic assist motorbike flies by with the right wheels in hand without neither noticing
before help arrived and robbed him of any chance regaining the breakaway he was in.
