Wow Pawel! That is an amazing video! I want to thank you for taking the time to make this. I hope you can make many more of these types of videos on how to repair and disassemble Shimano's mechanical and Di2 components.
Thank you. I'm working on the content. I have at least another 8 lined up. But it takes time, and I can only make videos in the evenings or over the weekend.
Nice video, looking forward to your next content. Btw, do you have any experience with new 12sp di2? Is it better sealed/greased? Any video regarding that comming? Krzysiek
Yes, I do have some experience. There are some improvements, but overall, they are using the same sealing technology. IMHO, the best sealed Di2 is Dura Ace RD 9070.
Another excellent video, I’m binge watching your stuff, cannot get enough. I wish I had found something like this 10 years ago, but better late than never, I still got a few of these 11speed’s around. I’m assuming there is similar internals in the di2 RX version as well? I have a mech that sounds like grinding gears. I feel confident in taking it apart and all, not sure if I can find spares for it if all the teeth are mangled. Would you consider doing a video on a front mech? I was in the middle of taking one apart, but same issue, I have a broken shaft, and was thinking about casting something myself as an experiment, as I cant find spares for that. But anyway, thanks so much for the excellent content, I love this.
The broken front derailleur was posted to me yesterday, so the video will be up soon. I think I need to take a couple of weeks off at work and do a massive dump of my knowledge on YT ;-). Be patient, I will cover all Di2 derailleurs, and I'm finishing 12s RD video. This should be up Thu/Fri, then I have Gravel, MTB, Front derailleurs, maintenance, fault finding, batteries, the list goes on....
@@Di2_GP oh my, batteries would be awesome as well. I dabbled into batteries a bit, 50% success rate :s I am so curious about you, where do you come from? I mean work wise, you obviously have lots of experience with this, can tell how confident you are handling the parts. Is this all self thought? I am so impressed I cant begin to tell you that, and really thanks again for the great content.
@@hmudesign Haha, thank you. Since I was 8 years old I would spend my free time at neighbours garage, helping with cars. When I was big enough I got a motorbike, then car, etc... I always had can do attitude, Then in 2013 I got into cycling, and the rest is a history... These components are built and assembled by people, it can't be that hard. I currently work as Product Sustainability Lead focusing on sustainable materials and product features. Education wise; computer systems and networks, with specialisation in electronics. But that was decades ago :-) I prefer self learning, as you can focus on important things.
This is seriously impressive skill and the video and explanation were excellent, thanks. I've done a lot of repairs on bike parts that would have normally been thrown away, but I think there are many steps here that are beyond me, even though you make it all LOOK relatively straightforward. So I'm going to pass on this one. How do we donate our broken Di2 derailleurs to you?
Either contact me via email or thru Instagram. I'm happy to cover postage, pay you something, or donate money to charity. I have more content on Instagram, but I've learnt it's not easy to follow.
Which model are you working on? For Dura Ace and XTR the closer to A pivot, you can remove by lifting covers and tapping the pin out. For 105, Ultegra, GRX and XT you have to drill 1.5mm pilot hole and then tap the pin out. pin closer to pivot B has to be drilled out, except for XTR. By far the best derailer for disassembly is XTR. As everything is held in place with grab screws. XTR, XT and GRX RX-817 share the same body geometry. You can swap servos, from GRX to XT/XTR. But XT/XTR 1x set up works with road and GRX shifters.
There is often a lot of LockTite on those screws. Without the heat, it is difficult to remove them. Also, using a security screw is not user-friendly. The majority of people who would work on bikes have Torx 8. It makes it easier for the next person, and shows people the derailleur was already worked on. Nevertheless, give it another 2 years, and it will be illegal to use security screws anyway. EU right to repair, and Eco Design!!!
Best Di2 rear derailuer repair video of all time
Haha, thank you. Not much competition out there to be honest :-)
Thanks for sharing
You have the skill and dexterity of a watch maker ❤
Thank you
You are Genius!!!
You are too kind. I just have some spare time, and I'm nosy ;-)
Masterpeace. Watch out for ninja-guys from Shimano;)
Very interesting and informative, best video on Di2 repair
Brilliant video and repair. It is great that you can repair these expensive components. Great service 👌
Thank you. Hopefully, my videos will encourage other to take on Di2 repair instead of throwing them away.
Brilliant work. Eagerly waiting for front derailleur repair :)
Coming soon, I'm just waiting for one to be sent. But before I'll be posting 6870 repair.
I actually have one, but it's a a broken cage, the servo motor is perfectly fine @@Di2_GP
@donoldduckben which cage? Are you talking about the inner link? The part that hooks on the servo axle?
@@Di2_GP I'd be more than happy to send you a pic

@@Di2_GP I really appreciate the effort. I'll shout you a coffee next time we meet....
@@ivanradoszyce8183 I'd appreciate if you could spread the word. More subscribers will give me more motivation :-)
@@Di2_GP Do you live in Poland?
@kenjisanful I'm in the UK, but I'm originally from Poland 🇵🇱

Do you know how to get the blind parallelogram hinge pins out? That's the part of my derailleur I want to disassemble for custom finishing.

For Dura Ace and XTR the closer to A pivot, you can remove by lifting covers and tapping the pin out. For 105, Ultegra, GRX and XT you have to drill 1.5mm pilot hole and then tap the pin out. pin closer to pivot B has to be drilled out, except for XTR.

@@Di2_GP I have the grx 815 rd. I was afraid you'd say I'd have to drill holes.
@@popejbryant only small one, and as you're going to either re-sprsy it or polish it, warranty should not be an issue.
Instead of mashing the security screws, buy a tool case of bits, the one you want is usually in there somewhere.
There is often a lot of LockTite on those screws. Without the heat, it is difficult to remove them. Also, using a security screw is not user-friendly.
