Holy sh*t mate! Nearly fell off my chair there! Many thanks for the shout out! 🙏 As a die hard Di2 fan I’m looking forward to more videos on this topic 👌

Thanks for confirming the use of the Shimano SM-BCR2 Battery Charger as a means of updating Di2 firmware. For some reason my laptop didn't want to play along, but I was able to upload the firmware and change settings from my desktop PC. Many thanks for clear and complete instructions.

This was terrific. I just got my Di-2 in October and this made it really easy to update my firmware and program my device. THANK YOU!

Gotta love it, that you JUST got a new bike and you are already creating awesome content of the tech used on the new bike. Really cool. Who would've thought 20 years ago, that one day we would be connecting our bikes to our PCs and updating the firmware on some of the components. Pretty crazy (and technically advanced) world we live in :)

Thanks for the excellent presentation on this one Shane! The screen capture on the side was a perfect inclusion.

Wow wow, you are the first and only Di2 video tutorial that actually helped me figure this programming thing out! I can't thank you enough!

Very nice video. I have a TCR on order and I didn't realise that it didn't come with the wireless module so that's very handy to know before I lay my hands on it. Looking forward to the next video with installation and configuration.

Shane you legend!!! I'm an IT quarmby, however I've managed to activate the 'A' buttons on my Di2 thanks to your video. Cheers

Thanks, got my first DI2 bike today and had no idea how to get the extra hood buttons working. Got it done with your video.

While I don’t have Di2...yet...I greatly appreciate the video Shane. I just used your video to setup the Kickr Climb (double tap to return to level and trainer difficulty/wheelbase adjustment) as the instructions were lacking. Keep up the great work!! Cheers and Happy New Year!

Great video Shane! I'm going to be updating my Di2 firmware via USB this morning and will install the Ewok this afternoon when it arrives. And then I'll program those buttons! Thank you!

What’s nice about the wireless unit when you get it is the ability to send your gear ratio data to your garmin head unit. It will show what gear you are in front and back and after the ride it shows how many gear changes you made, some useless info. It can also show your battery level on the Garmin which is cool as you charge it so seldom, its really nice to have. Also check out the auto and semi auto features that are programable from the e tube software. In semi auto when you change front chainring you can set rear gears up or down to get a better ratio. In auto you only use rear shifter and front will change automatically to keep the ratio. In e tube you can play with when it will shift the front mech. Just wish there was a bit more options there. Quite nice! These modes are also shown on Garmin and changed via the junction box. Enjoy. I love my Di2

Looking forward to the Di2 series. Hav the same Di2 set on my Canyon, but not using any wireless module so far. So will definitely learn along the way. 👍

Thanks Bro, you rock! followed it to the letter. Just got my new Specialized di2. I know more than the bike shop owner now. Pays to be a techie.

DI2 is great stuff and I have used it for over 3 years. Instead of the WU111, I have used the MT800 XT display. This does the same job as WU111 (wireless unit), but shows the gear your are in and also gives a bleep when it is going to change the front derailleur. This is an awesome addition if you are using the syncro gears. Having 3 ports, also makes the wiring a touch easier if you are using sprint shifters or climbing switch.

I switched from Ultegra DI2 STI to GRX DI2, that video made my day - IT WORKS - THANK YOU VERY MUCH!!! - Same to Rides of Japan

Great video. I was unaware that one could use the battery charger adapter to connect to e-tube and thought I could only get firmware updates at my local bike shop. Too bad Shimano doesn't support Mac, but I borrowed my son's Windows laptop and used your instructions to successfully perform my first home based update. Thank you.

Well done! This worked and I'm psyched!

Awesome, thanks for the video, just received my Di2 bike so could use plenty of info to setup gear exactly like I want it.

Thanks Shane...Just downloaded all the software and thought this was going to be an all day affair. Easy Peasy!

Fantastic again Shane. You're a bloody legend

Nice Shane, always enjoy the little subtle things in ur vids mate. Favourite this time was the instinctive web search string, just caught yourself in time. Definitely curious to see what 'that' search would have coughed up. Early Di2 had a reputation in my group of issues on rare occasions for firmware updates so I've been wary about them (irrationally). But I'm keen to set up the A buttons so will try it. Cheers

Thanks.... great piece of info. Keep them coming please

Keep rockin it Lama. You are the best!!

Hi Shane, one little quirk using the PC connection, when all checks and updates are complete use the Disconnect Tab to disconnect the PC link to Di2, important step! I didn't do this the first time I connected by PC and I 'frooze' all components, couldn't re-connect, had to go to the shop to debug and re-install software/firmware. This doesn't happen with iPad...but I'm not an Apple fan...so , Disconnect the PC link then unplug the cable from the junction box... Happy New Year...great channel, love it up here in the northern hemisphere!

Hi mate..i just wanna thank you so much for making this video, this video help me a lot. I pray for you to have a good health and enjoy your ride. Tq very much from Malaysia..😊

For anyone interested in these numbers, I charted my Di2 battery decline curve over a two-month period with the following results starting with a fully charged battery (100%) and running it down to 20% (8363 total shifts; 976 miles; 55 hours riding time). The straight-line graphs for a fully discharged battery (0%) would have been close to 10,500 shifts (front and rear combined); 1200 miles; 70 hours riding time. Hours and miles are less relevant on battery drain than cumulative shifts since riding styles and terrain will impact shifting and saddle time. Data were collected on Garmin 820 head unit from 23 rides during a period of hot/warm weather (August & September) in southeast Texas (mostly flat) and riding with a group. Average ride: 42.4 miles; 363 shifts per ride (24 front & 340 rear). Bike: 2018 Canyon Ultimate 8.0 CF SLX Disc Di2 (new in June 2018) with Ultegra groupset.

Thanks mate! Just what I need 😎

Fantastic! Now I have one more thing today to tinker with.

Shane thank you so much. I have tried first via the iPhone app but couldn’t connect. Then I watch you and I have the batt charger and done accordingly. All my components needed an upgrade. I believe now after all these updating the iPhone app of e tube via the Bluetooth LE will be able to connect. Very useful

Great video. So helpful and much better than using the app. Thanks so much and keep the brilliant content coming

Nice, new bike looks mint!

Thank you, I wanted to buy BT module first, but this is right what I need.

Soo helpful, thanks mate!

Am I the only dummy who didn’t even know I had those little buttons under the hoods?! Safe to say now thanks to this vid all my components firmware are up to date and I can now shift my rear cassette using those sneaky buttons! So thanks! Looking forward to hearing your opinion on the E-Tube wireless unit and whether it’ll be a worthwhile investment for me as well.

Thanks - really helpful!

Im not really into cycling, but I just find it pretty crazy the amount of tech in something I thought was pretty much tech-free. wow

Hi Shane. Thanks for a no nonsense, comprehensive and well made video (a rare thing on UKposts these days). Can't wait to play with my build (on order) #colnago

Really great video, thank you.

I found it very easy also. But you will love it even more once you start riding it.

If your making a series of DI2 videos, thank you, thank you, thank you in advance!

Shane - the subtle search for USA lawyers was gold. It had me laughing

Good to see you work through this setup of Ultegra DI2 disc brake so i know what to do (or not to do) when I maybe get one. No macOS Software is 👎

I’ll be watching all of the series of Di2 videos even though I don’t have it then I’ll know what to do when I do get it 😂

Great vid! Thanks.

Thanks a lot, helped me.

I found myself compelled to update the firmware on my Shimano Di2 Wireless Unit (EW-WU111) due to significant battery drainage issues. It's quite surprising that Shimano continues to allow the sale of units that are essentially five years out of date, lacking crucial firmware updates right out of the box. With the firmware now updated, I'm cautiously optimistic that the problem has been resolved. However, it's ironic that a device designed to excel in wireless connectivity was, until now, performing poorly in its primary function. Kudos to Shimano for your customer excellence.

If one is looking for support from Shimano on Di2, they always ask you to connect the unit to the PC vs Bluetooth. You get more information from the PC software. Curious to see how much customization you can do with the A button on the Wahoo bolt. My right A button on my Garmin is setup to change screen, single tap forward and double tap backward. Left A button as a lap button, very handy for training, no need to take your hand off the handlebar to reach the button on the Garmin unit.

never knew I had those little buttons!

Excellent. My Canyon Aeroad didn't come with the EW-WU-111 either. When I got it I put inside the frame by the bottom bracket. Apparently they can go anywhere in the system. I find the A buttons stiff to press so not really suitable for gear changing. Worth trying if you haven't done so already is Synchro shifting where you only use the RH shifter. The front derailleur shifts automatically.

Thank dear, you are the best

Disc and di2.... never change a cable again?

Have seen a couple of posts about the first update of firmware over wireless bricking people's systems. There is a definite bug in the set up in that, the first time you connect the EW-WU111 and connect to it over wireless, if there is a firmware update available it will automatically try to do it wirelessly and that invariably crashes and "bricks" the system. However, like most smart designers, there is a reset possible, you just have to disconnect all the components; shifters from the function box and derailleurs from the derailleur and then reconnect them and it will reset the system. The idea that a failed firmware update would actually destroy a battery is a bit daft as it is just a set of instructions in the device. Safest thing to do is to ensure the firmware is updated over the wire using the charger before installing the EW-WU111. Rode mine out for 100kmsa yesterday and am super happy with it. There is a bit of lag between changing gear and that change being updated to the head unit display on my Elemnt Bolt (about 1 1/2 to 2 secs) so am interested to hear if there is any lag once you set up the 8070 hood buttons as shifters if it has to go to the wireless module, be read and then command the derailleurs. Am super happy with it though! (edit, just watched the rest and see there is no lag between button press and derailleur move, nice!)

holy shit!!! awesome!!

When you get the wireless part you'll see there is a tablet and phone version of the app. The tablet version has extra diagnostic functionality that lets you skip buying the fancier usb link adaptor

I had the buttons activating the shifters for a while but found I rarely used them given your fingers are right next to the actual shifters when you are on the hoods. I think you’ll go back to them changing computer screens. I like the pressing of the buttons on each side to automatically change from big ring to small ring (and cassette adjustment) when coming to a stop.

Thank you so much for this video!!

Welcome to the Borg!

Laughing my socks off with the 'Di2 lawyers' youtube search 😂👊🏻

I built my DI2 bike from parts rather than going out and simply "buying" a ready built DI2 equipped bike. That was much more fun and educational.

Very cool. I have the 9070 Di2 so I imagine I can activate the hood buttons as well. Unfortunately, I can't program them for my Garmin as I need the Ewok thingy as well as the latest generation e-tube battery. Both rather expensive options for minimal benefit.

If you do try to use the ew-wu111 and the mobile app and have rendered your di2 unresponsive just disconnect the battery for max 30 sec(and possibly wu111), reconnect and use the charger to connect to pc and restore... Had to do that a couple of times.... /o\

Today I got the battery low message (20%) on the Garmin. These are my stats, ridden from fully charged to 20% (80% used) of the battery: Rides: 9 Shifts: 12450 # front shifts : 461 (4%) # rear shifts :11989 (96%) Time: 32:21:23 Distance: 865.17 km Ascent : 13851 m

Hi Shane, nice vid, did the firmware updates using battery charge to windows laptop no problems, If anyone with a TT bike has the new single button di2 for full synchro shifting any advice welcome as that’s what I have to race my tri’s next season and need to work out best set up ?

Just a head up in regards to using the charger cable as a PC link and doing firmware, don't let the PC going into hibernation. I had this happen when I first got my bike with DI2 and it bricked the unit. I had to get the full program unit and re install the firmware on each component.

Not a di2 user, but I did pick this tip up from browsing cycling forums: Charge the battery via a pc instead of straight from the wall. For whatever reason, sometimes, charging from the wall makes the system think it has charged fully, whereas in reality it has barely charged at all. I’ll see if I can find the source

Hi Shane, I would like to get to hook up my di2 to a computer (which I don't have yet) . Can you display gear ration, count shift, create a graph for the gear ration with the Wahoo Bolt?

Hi Shane,just a quick question,can I update di2 if I have the bar end junction box which is the we-as910,I'm led to believe I can but unsure for certain

Shane, I did update my 8070 rear derailleurs wirelessly. After doing the update the entire system did NOTHING I had to unplug the battery and plug it back in. Things worked fine & update was recognized by etube.

hi can you set the x switch on the left shifter to shift rear derailleur like in sram's axs.

Just to clarify, does that mean you don’t need the D-Fly wireless unit to program the hood buttons and instead use the charger to connect to the Di2 system via a laptop?

“How to tell trademark lawyers to get fu...” That was a really long typo.

Hi great video, but I have a very specific question on Di2 battery level appearing on the Wahoo Elemnt Bolt. Does it appear as a separate field that you can configure to appear, like you can with phone battery?

Just picked up the same bike, supplied manually are not to flash so thanks for the video..... Side note do you use / recommend any frame protection products?

Sir can i updates via phone?using etube apps and shimamo device bluetooth to connect to the phone?

"how to tell trademark lawyers to get fu.. DI2" HAHAHA, EPIC!! excellent vid, love the techie side of things and di2 seems to deliver generously :) question, do you get anything different on duraace di2 in terms of wireless units, etc... or are the parts the same?

Hi, can you do update on the new firmware update. Also, any idea how to troubleshoot the mobile app to Di2, it always says poor connection and therefore cannot update software. Thank you

Have you enabled synchro shift yet? I didn’t think I’d like it. So for months I didn’t even try it. But once I did, it worked so incredibly well that I can’t imagine not having it now. (Synchro shift is basically an automatic front derailleur. You just shift with the right lever and as you shift into a harder gear, it’ll automatically go onto the big ring and back up two on the rear. So it’s the next available ratio, always the most efficient, never cross chaining.) Seriously. It’s brilliant. You can still manually control the FD if you don’t like what it’s doing. But I’d love to hear your thoughts on Synchro shift.

Could you tell me if you can shut the di2 off? What does it do when you continue clicking the button, when the LED turns red and stays on? And when you click the button again, the red and green LED turn on but go off afterwards. I just bought a di2 bike and im curious, but cant find it annywhere. Thx!

HAHA! I guess it's a day for shoutouts! Thanks Shane :)

Hi Shane. I came across your awesome video by coincidence, as I was trying to figure out how to update Di2 firmware, but I was unaware that I could check the rear cassette, and the garmin pages from the upper levers. Now ... my question is: does my Di2 R9150 need the EW-WU111 or not to program the buttons on the levels? Thanks in advance.

I bought a Focus bike last year with di2. Did the same upgrade to add ant support, but found that when I installed it, it didn’t work. The di2 battery that came with the bike wasn’t compatible. The moral of this story. Check the compatibility charts to confirm your battery model will work with the wireless component.

Hi buddy I've been using di2 since 2012 and never new you could do any of this I've always taken it to my LBS but not now Also your assiomas I just some yesterday and on my ultegra I font need the little washer. Have you found the same now you have a different group set. And by the way the assiomas are very nice piece of kit.

Welcome to Di2. I got it last summer and love but... i can’t believe how Shimano doesn’t support Macs. Was locked out on the first firmware update and change of password.. had to beg a neighbor to use his PC.

Shane, I want to get into indoor training (swift/rouvy) since I can no longer ride on the road due to a degenerative eye condition. I can't afford to purchase a new trainer (I really want a Kick Snap or core). I found a first generation kicker on eBay, do you think it's worth purchasing a used unit or wait until I can ave up the dough for a new trainer?

I wonder if we could connect those A Shifters to Zwift, so when you press the button, you use your power up, or perhaps press both to give wide spread Ride Ons.

i think the EW-WU111 can only be updated via blutooth. and usually this goes pair shaped. i have a SM-PCE1 handy if you need it Shane.

Do you have to have a Garmin? I have Wahoo Element Bolt will, will I be able to have some function on the Wahoo?

Hi Shane, have you found a way to program your 'A' switches so that you can control your GoPro camera? It would be excellent if you could start and stop recording on your GoPro using the 'A' switches.

I think we can all agree trademark lawyers need to learn how to get fu... nctional Di2 firmwares up to date. =]

if electronic shifting is the pinnacle of performance I wonder how mechanical shifting works against hydraulic rotor shifters

Shane is it possible to have your di2 battery detailed on a page on your wahoo bolt? Can’t see this anywhere Thanks

Did you not haveto do anything driver wise with the BCR2? Ive tested on three different computers and it wont work. They dont recognizer the charger even if i install drivers manually...

A small downside of having the junction box in the handlebars (as opposed to under the stem with the older unit) is that you can’t use a bar end mounted mirror, since in Oz (and I suppose the UK and Japan), you want your mirror mounted on the right hand bar end.

I NEVER do updates via wifi or post download without a fully charged battery. Ive bricked tech over the years and luckily recovered a couple. I love but i still have a cable network at home connected where possible its never let me down.

Welcome to Di2 world. *Spoiler alert* maybe you will never return to the mechanic world ;)

Update: E-TUBE will no longer connect via the SM-BCR2 :(

Did you get di2 voltage on your volt? I cannot find it anywhere. I upgraded my new '18 TCR to di2 after a yr of trying to get to shift well with cables w/o success. Di2 worked straight away. Only real headache is that i cannot seem to find battery voltage in the fields or sensor info. Have ratios but no voltage? Help? -U10

Why the bluetooth module isn't standard in the junction box these days is beyond me, you've also got to love not having mac support and a user interface that belongs in 1995.

Does anybody know if the Wahoo ELEMNT bolt works with the wireless DI2, for battery charge status, what gear you’re in and being able to change pages with the A shifters? Also I was under the impression that the latest DI2 battery had the wireless connection so there was no need to buy the additional connection piece?
