Wrong on all counts. Weather makes little odds, I'll do 250 miles over 3 days this week and I bet it won't move off of the current solid green indication.
I plug mine in and charge it every couple of months or so. Not because i've checked it and it's run down, just because it's quick and easy and only takes half an hour or so :-) and i do lots of miles..... in all weathers....... Rich_W said:

How much of a pain is it to carry a spare battery in a pocket/saddle bag?

You're obviously very anti Di2 and will have no good to say about it.
All batteries can be affected by cold temps, car batteries have been known to fail when the ambient temp drops, but that is usually the final sign that something else was failing.
I'm not anti, so much as unconvinced of a need. Seems an additional complexity for very little benefit. Plus the fact that more than once I've had a flat mobile phone when I need it, so what hope when I forget to charge the Di2 battery.

And the fact that when it does run out, there appears to be no failsafe option to manually put it into a middling gear to get you home.
I see WHY people like it, but do I as a reasonable rider NEED it and the added costs?

Do people need aero wheels, aero frames, carbon frames? People want stuff, people buy what pleases/suits them. I'm aware of both sides of the discussion, I'll stick to mechanical on the CX bike but for the road bikes I'd be Di2 all the way and the next bike will be Di2 or even maybe eTap.

You get plenty of warning that it's running out. First it puts the front on the little ring and won't shift back, then you've got plenty of shifts left on the rear to get you home. I don't think anyone has ever managed to run one completely flat....
I didn't get any warning when my rear derailleur cable snapped...Oh wait, that's mechanical so it can't have gone wrong!

WRT to Aero wheels, helmets etc (and I say that as someone who had Zipp 808s on my TT bike and also owns a Giro Synthe helmet) Is that they are a quantifiable performance gain. My mindset has always been that I'm not gaining anything from Di2. That like many, I can set up indexing. And it be fine. Di2 may give perfect shifts every time, but I've not had an experience where I've felt my shifting was sub par. It might need tweeking occasionally, but I imagine Di2 does too.I suspect that I'll need to ride Di2 and see if I like it.

I cannot remember ever having a rear mech cable snap tbh. In probably 25 years of geared bikes. I guess it must have happened. But I can't remember it. Brake cables were common when they were ste in the 80s.Oh wait, that's mechanical so it can't have gone wrong!
Maybe you aren't buying decent cables
I've had rear mech cables snap ... and only after a couple of thousand mile At the shifter end. This was on DA9000 and happened three times before I had the shifter replaced by a 9001 under warranty. There is/was an issue with 9000 shifters breaking cables but Shimano didn't make any noise about it!
Anyhow, I have 2 x bikes running DA9000 with DA cables and the shift perfectly ... I have yet to try di2 but rarely hear a bad word said about it. For me it's the added complexity I'm shying away from ... in fact I'm more tempted by etap than di2.
That said, the most benefit I can personally see is by having di2 on my winter bike, as it doesn't take long, even with new cables, for gear shifts to feel mushy all too quickly.

My boss did; although he is a prize bell end sometimes.
Couldn't quantify what he didn't like, and had a few issue's... he didn't charge the battery first time out so couldn't go out (so he got very angry) one of the cables wasn't in correctly and too fking lazy to take back the dealer to have it set it up properly. Also, it was a different colour to his other Trek, so he px'd it at road bike exchange in Kingston.

Thinking about it, I reckon 100% of the negatives about Di2 I've heard are down to user error!Couldn't quantify what he didn't like, and had a few issue's... he didn't charge the battery first time out so couldn't go out (so he got very angry) one of the cables wasn't in correctly and too fking lazy to take back the dealer to have it set it up properly.

The new Ultegra Di2 is due out very soon, according to Weight Weenies
100% Di2 every time..! I've never met anyone who's upgraded to Di2 from mechanical, and has gone back...
I ride several times a week in all weather, and have never had a battery on a Di2 bike go flat. Once when I didn't check the charge level before a ride, battery ran low 20km from home, so I just had rear derailleur.

You get about 150 RD shifts once the FD has stopped responding.Teebs said:
