Or a RD that's been damaged by contact in the Porte crash.
It's possible - he gets a glancing blow from DM's feet on the drive side. That said the problem he has is quite a few KM's down the road, and as the NS mechanic fiddles with it it limply slides down in to the smallest cog. What luck - damage to the mech that only kicks in six km down the road, and then the mech is still aligned, but just 'dead'.
Really think mechanics are forgetting to charge Di2 in the biggest race in the world?
I'm not suggesting that. Could be a duff battery caused by some production issue. Froome had a similar issue it seemed, he had time for a bike change.
Even if there was something wrong with it, when Aru attacked Froome with a mechanical he was a villain, but when Barguil attacked UrĂ¡n with a mechanical he was a hero...
Seemed to be stuck in whatever super spinny gear he was using at the time - not seen much on it the exact cause because the consequences were more interesting I suppose.
