I meant both wired and wireless. I hear that the shifting is faster and smoother than cables, but my cable shifting feels perfectly acceptable as it is. I can't imagine a slight improvement there is worth the hassle of dealing with batteries dying, servos wearing out or getting shorted by liquid ingress, or the security issues of wireless that the article mentions.
But then, maybe I'm just a Luddite.
I switched my bike to Di2. Best thing I've done. I was tired of shift cables breaking.
Everyone always says that cables work great and are trouble free, but my 105 11-speed was a cable eater. Apparently it's a known issue with them, one guy I know replaces his cables every 6 months to avoid having them break during a ride. The last one that broke was installed by a pro and had less than 2k miles on it, and there was no warning there was any problem before the ride.
A few times I caught it and replaced the cable before it broke on a ride, but I've had breaks several times during rides. I never had an issue with my older 8 speed setup, so I think it's something to do with the bend the cable has to make in the shifter.
And even when the cable wasn't breaking, it felt like I needed to adjust the derailleur every so often to get it to shift juuuuust right.
Di2 has been set and forget, for the most part - I recharge the battery every few weeks. I haven't had to do anything else to it since installation.
It's so easy to operate, too. I know cables are also easy to operate, but electronic is even easier. Just tap the button or hold the button. The front derailleur auto aligns as needed, too. I spend a lot less time worrying about my drivetrain during and after rides.
You can also get information about your riding from it - how much time do you spend in each gear? I know I shift every 8 seconds, on average, which makes me think I might be shifting too often. (I also ride in hilly areas, so I definitely use all of my gears.)
Someone else noted the buttons I can use to control the computer. I have mine set to switch screens on the computer, and I use it pretty regularly. Nice not having to take my hands off the grips to do that.
I'm glad I made the switch, and I won't go back. I also built my gravel bike with Di2, and I'm glad I did it there, too. If people want to use cables, that's fine with me, but I'm really happy with the electronic setup.
And Di2 is becoming more accessible. No regrets here either. It's s luxury but one that's worth it.
I just spoke to someone I know whose bike has electronic gears. Batteries dying can be a real problem, but neither they nor anyone else I’ve heard of has ever had problems with liquid ingress or servos wearing out; I think those are largely fake scaremongering, at least on reputable brand bikes. In fact from what I’ve seen, water and dirt are more likely to cause problems for mechanical shifting than for electronic.
As for the shifting, the person I spoke to said yeah it definitely is noticeably better, but not so much better that they’d have bothered with it, if it weren’t for the fact that the bike they were getting only comes with electronic gears.
