[@rudevectors8018]

Brilliant video, extremely well done. I’ve just realised I’ve never come across a video that simply explained the shifter system in actual use. Thank you.

[@EricB03]

Awesome and glad it was helpful. It made sense in my mind so very happy that it does. Thanks commenting and have a great rest of your weekend.

[@SuperBardley]

Erik, thanks for putting the vid up, you cover a lot of territory in great detail. It is very helpful.

[@EricB03]

My pleasure and love di2 as you can tell. Hope you are well and have a great weekend.

Wow, that clamp on the carbon.

Great video. Thanks for all of the information.

[@EricB03]

My pleasure and thanks for watching. I love di2 among many other things. Disc breaks are an amazing addition to bikes also which I love. Have a great day.

Hi Eric, noticed your channel & watched this video about Shimano Di2. I just purchased my first Canyon road bike which has Ultegra Di2. It’s a super intimidating system… really enjoyed this video. Unfortunately, I do have a lot more questions & need help 🤦🏻‍♂️ Any chance to connect with you?

[@EricB03]

@@BehrozRasulzad post them here and will try my best to help you. Have a good one and enjoy the new bike.

[@robertoalfalla256]

Excellent Video. I have a current Ultegra Di2 with the Function button on the Rear Derailleur. It doesn't seem to have this auto adjust mode as you demonstrated. am I missing something?

[@EricB03]

As far as I know it doesn’t do that. You can still however do micro adjustments. To be honest though I hardly ever have to re-index using that mode. Thanks for the comment and have a great weekend.

[@hard2hook]

@@EricB03 Yes I just checked, and the auto adjust option is not available on my DI2 with the function on the rear derailleur. Bummer, it would have been handy to be able to use that...

[@EricB03]

@@hard2hook yeah but honestly you probably don’t really need it as I hardly use it. Thanks for the comment and happy cycling.

[@Psharma79]

Full synchro moves both front and back derailleurs.

[@EricB03]

Just let the front (up or down) depending on where you programmed it to move based on back location based on shifting back. Let me know if that doesn’t make sense.

[@47Seagull]

Excellent video. In particular I was intrigued with the calibrating procedure you used. I noted that you were in the small ring at the front, is this mandatory fro it it adjust correctly or do you also do the same procedure in the big ring?

[@EricB03]

@@47Seagull no not mandatory at all and I do it in the big ring usually and haven’t had any issues when in small ring. But usually small ring when going up hill so speed I am going is much slower

[@47Seagull]

@@EricB03 I have used the manual method and never been able to get a silent chain also tried the phone app adjustment with same results. Be interesting to try your method 😁

[@EricB03]

@@47Seagull great and hope it works as seems to for me. So much nicer what we have now vs 10 years ago

[@47Seagull]

@@EricB03 Followed your instructions yesterday, fascinating. Normally I have adjusted the rear derailleur manually with the shifter or through the E-project app, neither have been totally successful for me, although It could be the KMC waxed chain that is causing my noise concern. A quick 100 meter ride suggested that this method is more successful. Won't be able to tell 100% for a couple of weeks due to other commitments. I'll get back to you 😀

[@geethakafernando8215]

Hi Eric, loved the video. just wondering whether 'Derailleur Adjustments via Junction Box' works on newer 12 speed ultegra di2 models (ones without junction boxes - where all of that functionality is in the battery and the rear derailleur) Thanks so much

[@EricB03]

Functionality is in the detailed as it doesn’t have the junction box as you are aware. There is a button on the rear derailer to change modes, or do micro adjustments if necessary. Hope that answers your question and thanks for the comment.

[@jamespaul4362]

Excellent video. You made something rather confusing simple to follow. Thank you!

Thank you so much for the kind words and glad it was useful for you. I tried to explain it the best I could. Have a great day.

What is E-tube?

[@EricB03]

Shimano cycling app that enables you to go in and change the programming of the shifting parameters

[@holdencaulfied7492]

@@EricB03 Dude your video is great. All these bike snobs on Reddit are saying manual mode is better but I love the idea of never having to think about which chainring to be in. On rolling hills it's a constant thing to think about. I can't wait to get Di2 and use synchro mode.

[@EricB03]

@@holdencaulfied7492 whatever works for each person. I just like to shift on side and other can be taken care of by the shifting.

[@kentao4]

Thanks for all of this. Making my decision on SRAM vs Shimano that much more difficult lol. I had di2 on my previous bike but I’ve been tempted to give SRAM a shot since it’s harder to get caught without power since you can simply change batteries. I know it’s not the end all but since I have a MTB with those batteries, I should never be out of power! Nice video.

[@EricB03]

Thanks for the comment. Either way they both are great systems. Game changer for me and the ease of shifting is a joy. Take care.

[@l.d.t.6327]

you'll get a warning if you are at 10% battery with Shimano, and shifting will be limited to the rear derailleur from that level on. So it's quite 'easy' to remember when to charge your battery.

[@kentao4]

@@l.d.t.6327 already got sram. Thanks for the info

Waiting for my new DI2 bike to be delivered. Wow, there are lots of cool features. I think I may need to upgrade my Garmin computer now to get the additional cool features! Thanks for putting this vid together.

[@EricB03]

YES!!! Excited for you. Which computer you have? And you are welcome

@@jimgraham290 you are in luck I think: Shimano Di2 Integration www.garmin.com/en-US/p/112885 Like the Edge 1000, the Edge 510 now integrates with Shimano Di2 shifting systems5 to display your current gear on the screen. We’ve also expanded the integration capabilities for those Edge users with compatible Shimano Dura Ace Di2 systems by allowing them to directly control their Edge from the small buttons inside the brake hoods.

@@theripper121 as soon as you get it you won’t go back. It is a joy to use and best upgrade on a bike IMO and disc breaks are very close. Good luck with your choice

@@EricB03 Yes bought a bike during height of covid and getting back into it doing about 30 miles a few times a week. Only thing I could find at the time was a bike with tiagra groupset that was actually probably a size too big for me and has mechanical disk brakes. So a 105di 12 speed and hydraulic disk brakes would be a real upgrade.

[@EricB03]

@@theripper121 yes 105 is a good middle ground for value. A bike to big is worse than too small and been there. Good luck with getting back on it and know you will do great.
