The Di2 firmware stored crashing. The bike would refuse to vary gears, entrance or again. I must pull over and press the button on the rear derailleur with a view to get it to start out shifting once more. Time and again. No sample or repro steps, simply fully random.
I additionally obtained a spurious ‘battery degree essential’ error that freaked me proper out firstly of the race, however certainly the battery was absolutely charged and I used to be capable of get the shifters restarted via the whole race.
It may be on account of a firmware improve {that a} native store did earlier than the race. Is that this a recognized bug?
It didn’t look like in crash mode, as I didn’t need to undergo crash restoration mode. It did occur the primary time after hitting a small bump, presumably whereas sifting. The remainder of the occasions it occurred after a shift. A lot of the crashes had been in a really excessive gear. There isn’t any harm to my rear detailer and I’ve by no means had an accident or a lot as bumped my bike.
Would recognize any data or recommendation right here as it’s now fairly onerous to belief my bike or Shimano’s software program.
Not that I ever have, or will, EVER, trusted Shimano software program after shopping for the Ultegra energy meter crank set.
