i thought that even witb Shimano you have to use the wired version for those functions

Ah, I wasn’t aware. Appreciate the feedback.

Does your derailleur take a battery? If so I don't think you'll have those features. It needs to be wired back to the motor.

yes. The rear mech is battery powered. Thank you. I was oblivious to the wired aspect of the RD.

Yup. The only way for the motor and derailleur to work together to provide feedback on gear selection etc is to use the system hardwired.
 
Just got done upgrading my drive train thanks largely to this forum thread. My bike is a 2025 Orbea Wild M-Team which had been spec'd with Shimano M8100 components. My goal was to upgrade to an electronic shift, and upon hearing about the Bosch software update to enable the advanced e-shift capabilities I was sold.

So for anyone considering this path, the parts I purchased were:
  • Shimano XT RD-M8260 Di2 Wireless eMTB Rear Derailleur
  • Shimano XT SW-M8250 Di2 Wireless Shifter
  • EW-PS300 Di2 Wire for Bosch Smart System Drive Units - 1000mm
I then had to take my bike to the LBS to have the High Power Port (HPP) enabled, which I thought was going to be the primary challenge. As it turns out, it was a simple button click with the Bosch software tool even though the LBS had not done this previously and was cautioning that it may not be possible.

I am pleased to report that the system is working beautifully, particularly the gear change while coasting. Only have a couple of rides in so far, but will report back as I get more time with the new setup.

This is really useful, thanks.

How are you getting on with it since?

Does anyone know the difference in the deore Vs xt derailleur? I think the material is alloy Vs steel but can't see anything else.

Are there any functional differences that they don't have on the deore (m6260) one?

from what I gather, the derrailleurs are identical except for cage material (and therefore weight)

The Deore trigger doesn’t have the paddle adjustability that XT and XTR have

Well. Fun fact - after I upgraded to the Shimano wireless setup I decided that I should upgrade the Bosch controller to the Kiox 400C which one would think is straight forward. Alas, the shimano derailleur was paired with the stock Bosch controller and I could not get the Shimano hardware to pair with the new controller. So it's been in the LBS that does Shimano work this week getting sorted out.

Always something...

That’s not true. I also bought the Kiox 400C, and when I installed it on the bike, I had to reactivate the system controller and the Shimano XT Di2 rear derailleur. I was able to do it at home in 15 minutes, without dealer equipment.

Lol. Ok bud. Glad it worked out for you, but it did not work out for me. I took the bike to an authorized Shimano dealer and they had to hold the bike to reprogram the derailleur. So your "truth" is different than my experience.
 
Any more thoughts/experience with this from those that have it?

Looks like cost is roughly €590?

Shifter €130
Cable €70
Derailleur €390

I really would have liked the XT version but struggled to justify the €700+ price tag and instead went for an 11 speed Cues version which cost €439,75 at the time for the individual parts from Ebike24. They do the same now as a kit for €412 but not currently in stock" In retrospect I regret not having gone for the more expensive XT shifter at €190!
Shifter €120
Cable €70
Derailleur €240
It works very well and love the auto freewheel downshift in the M+ mode.:D

Thanks for the reply.

Just weighing up the different options. Why would you like the xt parts now having had yours for some time?

Apparently on the the XT shifter you can individually adjust the position of the paddles to suit your hand whereas the Cues one is fixed and for me is not entirely comfortable to use (I have arthritis in my right thumb) .
Also I have now found the XT shifter at other German online shops as cheap as €130 so may upgrade anyway and would be a no brainer at that price if buying the complete set of parts, apparently there are no compatibility issues.:)

Ah so just the shifter, that makes sense!

Yep, very happy with the Cues derailleur:) and not at all worried about how heavy it is compared to the XT and XTR versions!

Is your motor bosch or shimano? Im guessing it's shimano? Im not sure that derailleur will work with a gen5 Bosch perf and give all the integration for freeshift etc

Just looking, i think the Cues only comes in 11 speed for di2, which isnt a deal breaker. It mentions it supports "Steps", which I believe are Shimano terms. Freeshift is also mentioned though.

I have a bike with a fifth-generation Bosch motor and a Shimano Di2 XT drivetrain. Everything has been working perfectly for four months.

Thats good to know. I think that's the one I might land on, but just weighing up cost/benefits at the min. XTR on a big fat ebike with a big fella on it makes no sense at all for example.

I had a good offer, so I chose the XT option. You might run into some issues during installation — you can read above, I described my installation process there. There’s especially a nuance with the connection cable and unlocking the port. But I’ve already explained everything above, you can take a look.
Overall, it’s worth it: automatic shifting works great in the city, while in the mountains I use the semi-automatic mode because the full automatic doesn’t work quite correctly there.

It is a Bosch Gen 5 CX and the Di2 Cues derailleur is the rd-u8050-11-speed, I have an 11 speed linkglide cassette. I get full auto, also M+ with freewheel downshift and of course manual.

€100 here?


Maybe i-spec no good
 
Question :

Will a Di2 powered wireless rig e.g. RD-M8260-11L etc. work in simple derailleur mode - no fancy stuff.
Correct voltege supplied - Not a Shimano or Bosch bike.
Looking at the Shimano app it looks like you can add the Mech. and the Trigger.

Is there something in the system that forces there to be a Shimano or Bosch motor somewhere in the system.
Just want it to work like the Full-Wireless battery versions do - simple mech.

Prefer the wired/wireless because you have the option of Linkglide 10/11s and one (Cues RD-U8050-GS) has a medium cage. Not sure if Cues is designed for heavy duty off road though !?

Full-Wireless are all HG+ 12s.

That’s very helpful, thank you for your reply. I think I will wait also then as I am in no hurry. I am waiting for some YouTube videos on the install. There are plenty of the M8250 but nothing on the M8260 as yet.
On this forum, it only appears to be @Eifice that has fitted one. @Eifice , can you give us more details of the install please and if there was a Bluetooth addition that you went through please? Also any other things you had to do apart from the hardware fitting, paring for example, that would be really helpful. Thanks both.

it's been a while but I found this video helpful to get an idea of what is involved (in German but there are subtitles available)
