I’ve heard about several bike failures yesterday amongst the pros.
Jeff Symonds - broken crank
Matt Hansen - snapped brake cable
Heater Wuertle - Di2 meltdown
Any others?
I don’t think it was Heather’s Di2, it was her rear derailleur pulley came dislodged according to Fastyellow (Dusty Nabor) who saw her bike.
It wasn’t a Di2 failure, it was a pulley failure. AKA it was a mechanical failure in an electric system.
