Thank you so much for putting this together, it was very helpful! One part I stumbled on was my front derailleur was on the small ring, and, as I found out, when in the small ring the control system prevents the rear derailleur from going into the smallest cog. That caused MUCH confusion when I was attempting to set the 'H' screw adjustment. Once I figured that out I was rockin n rolling. I would consider adding a note to the video to 'be sure to set the front derailleur to the big ring' before adjusting the 'H' screw. Alas, I dring a beer for you. Ching Ching.

Had to change my rear derailleur today and was looking for a good guide that eliminates my question marks - your’s is by far the best I was able to fine here on good old KZread, so thanks for that man!

I watched your videos back when I built my first bike with an R7000 last year. Now I'm getting ready to build my new bike with Ultegra Di2 for the upcoming season, and your videos are still the best!

Perfect--just the video I needed. Very well explained--bien, merci beaucoup!

Thanks mate, I had my hanger set wrong before I watched this. Rest of video helped me out a lot too..

Cheers for video. I’ll have a go again at trying to fine tune my Di2. It goes through all gears when on big ring fine and quiet. But when your in small ring it doesn’t change great just catching, so then you adjust it so just enough to get in gear. Great you think. Go back to big ring go through gears again and you then have same problem Vice versa. Maybe my limit screws are upsetting adjustments.

extremely helpful video. I do appreciate your detail explanations and how to adjust H and L as well B nut, and incorporating completing system adjustment. Really great video. Finally I do understand how the system operates.

Very helpful installation video especially the 8mm Allen key hack for the B screw.

Great video. Helped me install my Di2 rear mech. Thanks for making it.

Super informative video, explaining a few question i had. Cheers from Denmark

really great explanation video. I learned lot about R8050 Rear Derailleur and setting up. Keep them coming....

brilliant video, thank you!

Great video. Helped me to adjust my Di2 derailleur without any problem

Hi Free To Cycle thank you for such an informative video. I replaced my old RD-6870-SS rear derailleur with a brand new RD-8050-GS (I have an 11-32 cassette) just a few days ago. I have encountered a problem though. Shimano manual tells you to select gear 5 to start micro adjusting the derailleur. Then start clicking inboard until the chain touches gear 4. I do that but I run out of clicks. The micro adjustments are there, a full 32, 16 each way. In my case I only get 9 clicks inboard (then if I keep clicking inboard nothing happens) and the remaining clicks outboard. I made sure that the high/low stops are adjusted correctly, that the rear wheel is true, that the hanger is correctly aligned with the hanger alignment tool and that the the front derailleur is also setup properly. When I adjust, I have the chain engaged into the the big chainring (in the front 50 tooth). The small chainring is 34. What could be causing this? I am currently stuck. Thank you.

Brilliantly done. Thank you!

This is by far the best explanation and guide for rear di2. Well done, and THANK YOU.

Awesome videos, man. Made installation a breeze.

You are so good. Thank you 🙏🏻

Really helpful, thanks!

A very helpful guide - cheers

You made this really clear and easy. But before doing so I have the task of hanging my front mount. It broke. Riveted on like your display. Any suggestions on purchase/install? Thanks!

Very Good explanation. Thank you!

Very good, I did have trouble with the front derailleur but had to shim it so it would work, The chain ring was smaller and at the bottom of the frame front derailleur mount so it would not center and it pushed out in the front when you tried to adjust the top adjustment. I think it will work but have not put chain on yet so waiting for the chain to arrive. I think its all set to go thanks!

Nice guide, thanks for taking the time to post 👍

Excellent again!!

A good video, i hit a pothole in Potterne and the rear mech hanger snapped off, mech in the spokes and ive gone from a Ultegra 6870 rear mech to a 8050, i seem to be having some setup issues, so will follow this and see what i can get done.

Good job sir! Thanks!

Hey @FreetoCycle ⚙, great installation videos for both front & rear derailleurs, I've installed an Ultegra Di2 on my Canyon Ultimate CF SL, (11-32 R, 52-36F) All seemed to be shifting fine before the first ride, when I when up my first decent hill, in first gear it over shifted and the chain came off, so I adjusted the limit screw so that wouldn't happen, then I was getting it to shift into first gear but it would stay there for 2/3 revolutions then come down to second gear, I then went on to the Etube app to adjust the gear (so I could see what was happening), I adjusted, and again it was shifting fine at home, but when I'm on a hill it is now upping in the second & first gears when going up hills, Just wondering if you ever seen anything like this??

Very helpful video and well explained! Top!!

Very helpful instructions! I'm looking to fit a bigger cassette on my R8050 GS derailuer. Shimano official guide says Max should be 32 but I saw others have fit SRAM 11-36. Can the Shimano mountain 11-40 fit without a road link?

Best how to videos hands down

Crystal clear explanation👍🏻…thanks!

Very helpful information!.. Thanks a lot for sharing.. Subscribed ;-)

Great videos man. It looks like I can build my own bike by using your videos. A question, which do we adjust first? Front di2 or rear di2 derailleur?

Hi great video thank you. Would 11 speed Ultegra Di2 rear derailleur work on a 10speed cassette?

I see that you over adjusted the derailleur by going down on the cassette but I have seen other mechanics do it the opposite direction. Does it matter which direction on the cassette u over adjust the derailleur? Thx

Well explained video subs 👍🏻

Cheers

Great video. I have a question. I have a 10 speed di2 dura ace and it seems that my rear derailleur is going bad. Is it possible to keep my front derailleur and upgrade the rear derailleur to an updated 11 speed dura ace di2 and 11speed cassette ?

@fbwsimpilot

Yes it is, but you would have to change your shifters to 11 speed and your chain to an 11 speed chain also.

How do you override the system to be able to use all gears on cassette when in small ring ??

Is this rear derailleur compatible with the 6800 series?

Which should be installed and adjusted first, front or rear derailleur? The front derailleur is used while adjusting the rear derailleur in this video so does that mean the FD should be installed and adjusted first?

Hello. Ive just replaced my rear derailleur. It’s moving fine when no chain is on, but when the chain is on it won’t shift! Have you got any ideas what this might be? Thanks

My bike chain does not come down to fourth teeth while in adjustment mood and it only goes to sixth teeth. What's wrong?

Hi may I know if there any issue the RD hit the cassete when the gear in smalest sprocket ? Because it hapen to me wh3n I change 8050 RD SS to GS, I use Y3E81600 inner plate and Y3E998080 outer plate
