I'm so torn about this. With a 1x drivetrain the shift modes don't do anything. So since I don't have a Di2 compatible suspension (who does?) or front derailleur, this little guy just shows me battery level and current gear. My Garmin does that too - and it doesn't go dark after 5 seconds.

But it's cheaper than a normal junction A and EW-WU111 combo, so there's that.

Overall it's well made and performs great - it just has features that many people won't ever use.

The joy of Di2

The brains of the mtb Di2 groupIt is a little weird having a small display on the bike, which I don't glance at too much, but being able to program shifting from my iPhone through the eTube system is nifty. Plus you can set a pair of preferences, perhaps a road riding profile and an off-road one. (If, like me, you often use your mtb on the road with a different set of tires.)
