DI2 Alignment/Tuning Your Electronic Shifting System Part Two

[@scotsmamil]

This simple yet effective video helped me figure out the low gear 'ghost shift' issue I was having recently on my DA 9150, perfect!

[@TTUVBALL]

this video along with part 1 are the best videos i have found for DI2 adjustments. Got these saved in my favorites list!

[@velotiqueBetterWatchSaul]

Glad you like them!

[@w4yland3r27]

Both of your shifting videos are so simple and straightforward. Literally better than any other di2 shifting video I've seen.

[@velotiqueBetterWatchSaul]

Glad you like them!

[@12GaugePadawan]

Your video is what gave me the confidence to finally go from thinking about it to reading about it to actually doing it! 👍🏻 🚴‍♀️

[@velotiqueBetterWatchSaul]

So glad to here this.

[@hayabusa27]

Hey man thank you so much for uploading this. I don't know anyone else who could have help me align this thing and only you and your vid came through. God bless you 👏🏻

[@velotiqueBetterWatchSaul]

Very kind of you to say.

[@krider7296]

Thank you so much for making this very informative video. Your explanation of how to set up the Di2 gearing system is the best I have seen. Very clear and concise.

[@velotiqueBetterWatchSaul]

Glad you enjoyed it!

[@jeffreyreed6056]

This was excellent and it finally made my Dura Ace 9150 Di2 adjustment essentially perfect. I would like to see a video on Q rings as that is what I am using, especially with Di2! Great job, easy to follow!

[@velotiqueBetterWatchSaul]

Thank you.

[@jimbo2112]

Best explanation on this I've seen ever.👍

[@velotiqueBetterWatchSaul]

Thank you. I'm glad you found it informative.

[@carly200]

Still one of the best videos (with great graphics) on DI2 Adjustment! (This is September 2021) :-)

[@velotiqueBetterWatchSaul]

Wow, thanks!

[@peterlaskiewicz8252]

This guy actually read the Shimano manual and described what it says! Good work :)

[@velotiqueBetterWatchSaul]

Thank you.

[@ryant75]

This guy is AMAZING! I watched this video every 6 month! Lol 😎 Thank you

[@velotiqueBetterWatchSaul]

Wow, thanks!

[@annoyedcyclist7746]

great video. I've never adjusted my FD so didn't realise there was that much to it. I've adjusted the RD and this is a great Aide Memoir for doing it properly. Thanks

[@velotiqueBetterWatchSaul]

Glad it helped!

[@DerrickMcKay]

Both videos were very helpful, thank you!

[@LaughingSaint66]

In 3 years I never knew front derailer could also be trimmed with di2 adjustment ! Although I’ve never needed to adjust it. Thanks

[@velotiqueBetterWatchSaul]

The wonderful thing about Di2 is once adjusted correctly it rarely needs attention.

[@LaughingSaint66]

Indeed and if needed can be done while riding which is so cool 🤙🏼👏🏼👏🏼🚴🏽‍♂️

[@alfred576]

Hi velotique, you are a legend. Really excellent videos, easy to follow on DI2 adjustment! Well done.

[@velotiqueBetterWatchSaul]

Thank you, again.

[@Brian-pk1ol]

This helped me a lot! It’s good to know how your gear works and that you can adjust it correctly. Thanks

[@velotiqueBetterWatchSaul]

You're welcome.

[@DougBruce]

Excellent, clear instructions. Thanks heaps. 👍

[@velotiqueBetterWatchSaul]

You're welcome!

[@ang2106]

Just used your technique and found it very helpful. Thank you!!!

[@velotiqueBetterWatchSaul]

You're welcome. Glad it worked.

Thank you for your videos im going to have a great ride.

[@velotiqueBetterWatchSaul]

Glad to hear it!

[@arkgl4d444]

Hey, thanks for the video, I can't adjust the electronic stop as you did, I get to the limit of the clicks before arriving at 0-0.5mm so I have already dropped the chain The low stop is well adjusted and the top one too, However, either I move away the upper stop of the chain and there I can approach the electronic stopper of the chain but impossible to have the right values by adjusting the two (high and electronic). I noticed a support screw is not even in contact with the frame, I'm lost, I don't want to send it to a mechanic because I tried to follow the Shimano manual...

[@arkgl4d444]

However, the gears normally pass forward and back but I sometimes cross the chains. it derailed like that in the collar, if I manage to adjust the adjustment of the electronic stopper Should the chain stay in place?

[@bagusla_alhamdulillah]

Thank you 🙏 so much good lesson

[@velotiqueBetterWatchSaul]

You are very welcome

[@bradsanders6954]

So. When I try to adjust the low clearance on the front, the screw turns freely as it should be moving the cage inward for clearance. But, the cage stays in the same spot.

[@DaMaziii]

First, thank you for your proper information. I have tuned up my Di2. However, when i change the front and rear gears quickly while i am going fast, it causes the chain to fall of from the rear derailleur in between the gap of the rear derailleur. this is happening just very recently. what is causing this and how can it be fixed? Thank you in advance

[@velotiqueBetterWatchSaul]

You"re welcome. It sounds like you need to adjust the High adjustment on the rear derailleur. The rear derailleur hi limit screw limits overshifting.

[@Dunc2222]

What size Allan (hex) key is required to adjust the rear limit screws? (I have Ultegra 6870 Di2, but don't have an Allan wrench small enough.) Thanks for the good video.

[@velotiqueBetterWatchSaul]

2mm

[@jacquesdeguise988]

Very good explanation

[@velotiqueBetterWatchSaul]

Thank you.

[@karlthorne]

Lovely video - I have Giant TCR (6850) -- when in big/big to set up trim using the FD shift buttons it won't get withing specified tolerance, however there is no chain rub and the FD auto adjust (low & high limits set with screws are within specified tolerances along with FD height to chain-ring and is parallel, FD shifting is crisp and lovely). I am guessing that this is common with some bikes with regards tolerances or is there something I might have missed or just simply not to worry about it? Many thanks.....

[@velotiqueBetterWatchSaul]

Sounds good.

[@karlthorne]

@@velotiqueBetterWatchSaul Thank you

[@velotiqueBetterWatchSaul]

You're welcome.

[@piet174]

Thank you very much for your very clear tutorial. I have the same Shimano Di2 system: FD 6870. Following your tutorial works fine until the fine tuning of the front derailleur. When I push one of the two switches on the left handlebar, after switching on the red light, nothing happens. Only the red light flashes when I press one of the switches but no movement of the shifter. What is it that I am doing wrong?

[@velotiqueBetterWatchSaul]

The flashing light indicates an error. To sure what adjustment you are attempting. It is not always possible to perform electrical adjustment..depending on firmware version. You might need to perform this adjustment mechanically using limit screws.

[@piet174]

@@velotiqueBetterWatchSaul Thanks a lot for your quick answer but maybe I was not clear enough about the red light. What actually happens was as follow: when the red light is on and I press one of the left shifter switches then the red light flashes 4 times off and on and after that it becomes steady red again. Is this an error indicating or is it due to the firmware version. If so is it possible for me to update this version or to correct the error?

[@velotiqueBetterWatchSaul]

If you run E-tube Project Software it will update firmware. You may be at the upper limit for that adjustment and it won't go further. Can you adjust in the other direction using the other Left Shifter Switch? Depending on what adjustment you are trying to make you may have to achieve it with the limit screws. You can only perform Top Position Electrical Adjustment on Ultegra Di2. Big/Big gear adjustment. See Manual for more details, page 70. si.shimano.com/pdfs/dm/DM-UL0001-03-ENG.pdf

[@piet174]

@@velotiqueBetterWatchSaul Thanks again. I used both left shifters. Result: no movement at all. Is it possible that there is no finetuning option of the front derailleur of this (relative old) system? I wanted to added two photos of the control unit but apparently this is not possible. There is a number on it: 7F0JKN0 4953 and also SM-EW6/A.

[@velotiqueBetterWatchSaul]

I am not sure of what the problem is. Check the manual in the previous reply. Are you using the E-tube Software?

[@araratjaff]

Hi there. My son dropped my bike the rear di2 mech went into crash mode. Now everything seems working fine apart from tit won't go to the highest gear (smallest sprocket). I watch your video and followed all the steps. But I can not shift the chain to the highest gear *smallest sprocket* Please need some help here. Thank you. Ararat

[@velotiqueBetterWatchSaul]

Are you in the big or small chain ring? Some derailleurs will not shift into the small-small combination. Or. It's possible that the derailleur hanger is bent. If bent it might be possible to re-bend or replace it.

[@rubiodrager5907]

Super helpful, the only useful video on youtube about this, many thanks! Just got a doubt, at the beginning of the alignment video when you position at 5 gear position, should you use the smallest chainring or the largest chainring?

[@velotiqueBetterWatchSaul]

Thank you. As for chain-ring position...it makes no difference.

[@marcocanosa]

wait, so that delayed ticking noise isnt normal when shifting the rear cog? learned something new today thanks!

[@velotiqueBetterWatchSaul]

Glad to help.

[@alfred576]

Hi Velotique, how are you? When I try to set the top position electronic adjustment for FD I am not able to set the gap to 0.5 mm from the inner plate. I click all the way, but the gap is still greater than 0.5mm. I have adjusted the low and high limit screws for the FD as shown by you. I have a Shimano Ultegra DI2 EW-RS910 junction box. What can be causing this and how do I fix it? Thank you.

[@velotiqueBetterWatchSaul]

Not sure why this is the case. You can find more details si.shimano.com/pdfs/dm/DM-R8050-04-ENG.pdf

[@sebastianzeuner1215]

Super helpful, the only useful video on youtube about this, many thanks! The only thing I don't understand is the very last step. I don't even get close to the chain when pushing the shifting buttons, before I come to the limit. What do I wrong? Why is the gap about 3mm at least? Thank you very much

[@velotiqueBetterWatchSaul]

If the shifting works to your satisfaction, without any chain rub or noise don't worry about this. If you need to address this you might need to adjust the actual front derailleur position.

[@Tchairdjian]

For the FD (I have the latest model R8050 Di2) Do I need to do both the mechanical adjustment using the H bolt, and the Electronic adjustments using the LED button adjustment mode? Actually, when I use the electronic mode, I can't see any movement on the derailleur.. very puzzled.

[@velotiqueBetterWatchSaul]

Yes. The electronic mode adjusts by less than one tenth of a gear shift. It might not be noticeable.

[@Tchairdjian]

So first I use the H screw then I fine tune it using the electronic method?

[@velotiqueBetterWatchSaul]

Yes.

[@jeoffreysaey7778]

If my chain is on the largest chainring and on the largest sprocket my chain goes off to te smallest chainring and try to get back to the largest but it doesn't work, what should i do?

[@trikpark]

Regarding "Top Position Electronic Adjustment". Does this apply to 6770 FD? When I enter adjustment mode, only the REAR derailleur micro adjusts. The front derailleur adjusts as normal. Nor "micro" adjustment for FD.

[@trikpark]

Also, when in the large ring and large cog, I have TONS of space between inside of FD cage and the chain. This may explain my difficulty in getting chain on to big ring towards the larger cog end of the cassette.

[@velotiqueBetterWatchSaul]

Set the chain onto the smaller chainring and the largest sprocket. Use a 2 mm Allen key to turn the low adjustment bolt to adjust so that there is a clearance of 0 - 0.5 mm between the chain and the chain guide inner plate. Next, set the chain onto the larger chainring and the smallest sprocket. Use a 2 mm Allen key to turn the top adjustment bolt to adjust so that there is a clearance of 0.5 - 1.0 mm between the chain and the chain guide outer plate. Move the front derailleur and the rear derailleur to all gear positions, and check that the chain guide does not touch the chain.

[@velotiqueBetterWatchSaul]

You are correct. There is no electronic adjustment for the 6770-FD. Follow the mechanical Low ad Top Adjustment Procedures.

[@Tchairdjian]

velotique in the FD R8050 Di2 model I only see one adjustment bolt - it says H. There is no L and H for the front FD correct? Are we supposed to use that same bolt for both Low and High Adjustments? Or am I missing something? Thanks again for all your responses so far.

[@velotiqueBetterWatchSaul]

Top or High adjustment is done with Screw. Low Adjustment is done electronically.

[@mroconnor6959]

Brilliant thanks helpful

[@velotiqueBetterWatchSaul]

You're welcome.

[@simondavies5590]

Hi Velotique - thanks for this. I have a question. I am finding that after I set the front mech low limit screw as prescribed, then when I have gears set to adjust hi limit the gap between out plate and chain is so large that the screw cannot close it anywhere near to the required distance. I have tried playing with the front mech position itself (not forgetting to losing the spacing screw when doing so). Any ideas? thanks again

[@velotiqueBetterWatchSaul]

Not sure what you mean. If the front is shifted to the big chain ring (Hi Gear) it is only a problem if the chain is dumping or rubbing on the front derailleur. Hi limit prevents this. Can you clarify?

[@simondavies1192]

@@velotiqueBetterWatchSaul hi thx for getting back to me - when I put in the big ring the inner face of the front mech is very close to the chain and the outer face is way out, to the point it struggles to chain down to the small ring - and also chain can come off easily. If I screw the hi limit to make the front mech go closer to the bike to close that gap there is not adjustment/screw turns can be made to set it even close to the prescribed 1mm or so gap.

[@velotiqueBetterWatchSaul]

Back off the high adjustment of the front derailleur. Go into adjustment mode and click the lever as few clicks as it takes to reposition it.

[@simondavies5590]

@@velotiqueBetterWatchSaul thx again for taking the time. I have tried that in the past and its run out of range. But I will try it having backed off the high as you suggest. very best

[@kristoffersimonsson3208]

I have a problem with my new bike with Di2 Ultegra 6870 where i have trouble going from the small to big ring in the front. This (mostly) happens when I'm in the middle of the cassette in the back. Electronically moving the front derailleur (as per the video) to its max limit I still have way more than 0,5mm between the chain and the inner plate of the front derailleur. Any suggestions?

[@velotiqueBetterWatchSaul]

It sounds like your front derailleur might not be positioned correctly or your crank arm is not fully tightened. Try to center the front derailleur on its mount. You should not have to set the electronic adjustment to this extreme. Did it ever work correctly. If it did then something has changed IE: loose crank arm.

[@davidparrott2090]

How about a video on front derailleur adjustment? This is an adjustment, which I have never fully understood , thanks!

[@velotiqueBetterWatchSaul]

My video "Fine Tune Your Gear" does cover some of these details. Let me know if this helps. kzbin.info/www/bejne/f3WthmWBideLmMk

[@skova265]

Please help me. Ma front mech looks likes it set up correctly, I even built the bike up my self and rode it 3 years. now I changed the front drivetrain to quqarq dfour, and can not get the shift from the small ring to the big ring to work. Please advise

[@velotiqueBetterWatchSaul]

Adjust the front Derailleur position. Make sure the Front Derailleur is parallel to the chain rings. Make sure that the outer plate is within 1-2 mm above the large ring.

[@MrDoodsz]

for the high limit screw mine won't make it all the way to the lowest cog. what can I do?

[@velotiqueBetterWatchSaul]

Front or rear derailleur?

[@MrDoodsz]

Oh my mistake. it's the rear derailleur.

[@jared7586]

Big help thx

[@velotiqueBetterWatchSaul]

You're welcome.

[@bnj2669]

My chain is not landing on the smallest cog , how many ever clicks. My chain is on the larger crank

[@velotiqueBetterWatchSaul]

Have you adjusted the the High Position Set Screw? Next use the adjustments in the Electronic Set mode to move the starting position of the rear derailleur.

[@bnj2669]

I did not adjust the screw in the beginning, later I tweaked around with it and got the chain to move. Gears are tuned now. Thank you for your reply.

[@NastyNatty48]

I still don’t understand the high limit screw on the rear derailleur?

[@velotiqueBetterWatchSaul]

It limits the range of motion on the derailleur to prevent shifting beyond the Highest gear.

[@NastyNatty48]

velotique for the adjustment do I turn the screw towards the plate. Do I stop turning it just when it touches the plate? Then back it off by one turn

[@velotiqueBetterWatchSaul]

Yes

[@Tchairdjian]

@@velotiqueBetterWatchSaul towards what plate?? I don't understand when to stop turning... please help

[@velotiqueBetterWatchSaul]

It is the point at witch the limit screw makes contact with limit stop on the derailleur body.
