i have had both DI2 and Sram etap and tbh they are both brilliant systems........if you like to fiddle, clean and build bikes, then sram etap is a no brainer as its fully wireless and the micro adjust to ensure good gear changes on the fly is brilliant...Seems this might be the electric groupset of choice for a while.
Thought I read somewhere it had more batteries and took more charging than Di2 ??
Any user experience likes/dislikes / problems ?
I have ultegra Di2 which I love.A battery on each mech and coin batteries on the shifters.
Apparently heavier and slower (marginally) than Di2 as Shimano only has the one battery.
The new di2 does have coin batteries in the shifters as it's semi wireless.
You might want to read a few more reviews though - what's important to you in your shifting ,?
what do you mean by this???I have ultegra Di2 which I love.
Looking at a new bike - in all probability Di2 won't be available - if it is no brainer I go for that. Just wondered what real world experience of Di2 was.
You're selling it to me!what do you mean by this???
i mean it changes gear, its quick at doing that, theres no cables to stretch, easy to set-up and adjust, you can add other changers within the system so hand movement is minimal, it can run your garmin, your garmin can show battery levels, what gear your in etc etc etc
Playing devils avocado, there is a bit difference between a wire transferring an electric signal to a motor on a mech (vs bluetooth transmission), and a piece of stainless steel pulling against a spring. Cosmetics and "clean looks" and transferability between frames / retrofit-ability, to take jowwy's point, favour bluetooth / etap, but an actual wire is arguably marginally more reliable for transmitting an electric signal, which is the point the Di2 advertising is trying to make.Yeah that slogan struck me as a bit defensive. "Wireless, except for that ... er ... wire. Which doesn't matter"

Yeah! Wireless where it matters until we've figured out how to make it fully wireless, then we'll have something new to sell you. I'm surprised that SRAM beat Shimano to a fully wireless setup a while back.Funny how I've heard quite a few folks promoting the new di2 in various channels (instagram/youtube) by saying "wireless where it matters" as a response to the public's expectation for something wireless and at least on par with sram etap
maybe its because they can be used on rim brake wheelsets 130mm dropouts, disc brake 135mm dropouts and 142mm.......and as the tolerances for all these are prob +-1mm, then the micro adjust is needed to ensure precise shifting...you will also get tolerances between cassettes etc etc that need ironing out tooSome questions here:
When Shimano say the new 2022 Di2 is semi-wireless, that just means it's wired, right, but with just a couple of less cables? But ultimately, it's wired.
Why do electronic gears still need manual micro adjustments?
TIA.
Ah thanks. I thought the adjustment was required, for example, while you're riding as osmething might go out of alignment.maybe its because they can be used on rim brake wheelsets 130mm dropouts, disc brake 135mm dropouts and 142mm.......and as the tolerances for all these are prob +-1mm, then the micro adjust is needed to ensure precise shifting...you will also get tolerances between cassettes etc etc that need ironing out too
