Shimano Di2 Wireless Bluetooth E-Tube Adaptor - Worth it? - Bike Maintenance

[@rosomak8244]

A nice demonstration of how much I don't need the hassle of electronics on a bike.

[@christeschke9844]

i had to do battery firmware update on my canyon grx. Showed up to a gravel race after charging the battery 3 days before with a dead battery and did it single speed.

[@dr.dalegonzales7609]

Absolutely best and most informative video on this Di2 setup. Great job!!

[@ribblevalleycyclist]

Thank you 👍

[@ruthhutchings6140]

Crikey! I didn't know how little I know about electronic shifting. Brilliant tutorial, great content.

[@ribblevalleycyclist]

Thanks! 👍

[@user-cx2bk6pm2f]

Wonderful walk through of Di2, thanks.

[@ribblevalleycyclist]

Glad you enjoyed it!

[@Thiaspeed]

Very interesting video. Is this device compatible with the GRX di2 rx815 ? Or do I need a different bluetooth adaptor ?

[@martinhotan8946]

GRX 11speed levers have a hidden button as well ...

[@Thiaspeed]

Does the GRX 11s work with this bluetooth adaptor ? Or is it a different one ?

[@thomaskuhn6541]

Good info, but at the start you said to get the proper tool for Di2 cables, and then you went and yanked the cable off the battery using just your hands?

[@ribblevalleycyclist]

I know, you’re not the first to spot that. Don’t be like Jon, use the tool 😂

[@geoffb7772]

Brilliant video, many thanks!! 👍🏻

[@ribblevalleycyclist]

Thanks, Geoff, glad you liked it 👍

[@jgmhermsen1]

Great content.

[@bdijns]

Hm, seems like my GRX Di2 doenst have all these features, e.g. no shift mode display option. Could be my elemnt roam or my groupset I guess. Good, informative vid tho!

[@christeschke9844]

update firmware maybe?

[@bdijns]

@@christeschke9844 Mine is. I think the road groupsets offer more options. Or it's wahoo vs garmin that makes the difference, not sure but it's also not that important tbh. :)

[@louholtman9202]

Use the correct tool bla bla bla and then the first thing you do is pull out the cable out of the battery by hand. When you have a little sense you don’t need that ridiculous tool. Just do’t pull on the cable. You figured that out.

[@ribblevalleycyclist]

Yeah, I spotted that in the edit. Guilty as charged!!

[@garygarafano8341]

I've found your videos very informative and helpful. Thank you.

[@ribblevalleycyclist]

You’re welcome. Glad you found it useful 👍

[@amritv6889]

I think, with 2024 shimano 105 Di2 system RD-R7150, battery BT-DN300, we no longer need EW-WU111 for connecting the garmin computer edge 530 or 830. Is this correct ??

[@ribblevalleycyclist]

Yes, you are correct. The newest Di2 systems include this.

[@mikecoffee]

This module isn't needed for the newer Di2 i.e the models with wireless shifters

[@ribblevalleycyclist]

Agreed Mike, did several takes of the intro, and the version where I say that.... and the price..... and where to get one for didn't make the cut, my bad! Should be obvious to the 12-speed users though. Thanks for spotting that, because I didn't!

[@mikecoffee]

@@ribblevalleycyclist no worries, good video, thought it was worth mentioning for people new to Di2

[@ribblevalleycyclist]

@@mikecoffee Cheers Mike. Yeah, hope people that’ve not used stuff like the app May get some help from it.

[@meibing4912]

My comment also - you should write this in the intro text to the video just below it so people don't get confused.

[@JohnLeichtman]

I live in a cold climate and store my bike in the garage. Will below 0 degrees Fahrenheit degrade the Di2 battery faster? Sometimes we see -20.

[@ribblevalleycyclist]

My experience is that cold only seems to affect old batteries. However, others may have a different opinion.

[@borasumer]

Store your bike indoors.

[@oxharp]

I just got a 12 speed di2 Ultegra with my new bike a Scott Solace Eride 20. I have never had an electronic groupset and was wondering what setting do you advise to start with? I am using manual at the mo but wanted to try semi and full syncro and not sure.

[@ribblevalleycyclist]

You know what, I’ll say full! When I first moved to electric, I switched to full, and it got on my nerves. However, I’d now miss it if I turned it off.

[@1971lemond]

Is this compatible with 9170 hydro di2 Dura Ace 11 speed group set?, and do I need the module for firmware updates for this group set?

[@stevedouglas3975]

Unless you have a Canyon Endurace which has the utterly stupid design of battery in down post(due to split seat post) and this therefore involves removing bottom bracket to access battery. Yes, you read that right. To access battery you need to remove cranks and bottom bracket. Madness. I obviously didn't do this when I installed the D-Fly unit, I connected to rear derailleur. This is with 6870 series Di2. However, in the not too distant future I will need to replace the battery as bike is 6 years old and now only getting around 500miles between charges and no doubt this will continue to reduce.

[@ribblevalleycyclist]

Crikey, that sounds like a right nightmare! You'd be gutted if you forgot to plug it in properly 🤣

[@stevedouglas3975]

Battery etc was installed when I bought bike new from Canyon so as yet I've not had to access it but I know within next 12 months I probably will. Mental design.

[@spdaltid]

Great video and presentation. I use one unit which I can swap between Di2 bikes. I only do this to configure the shifting as the E-tube computer interface is Windows only and won't run on my Mac. The battery remaining function on my head unit is handy, while the beep when I run out of gears on a climb is [usually!] amusing. These functions are otherwise not missed on the bike that is unequipped. Of course, wireless functionality comes straight out of the box with Sram eTap......and as well on the new Di2 according to comments on here, so there's that.

[@ribblevalleycyclist]

Thanks, Bob. As a Mac user, I have this issue too. Also, I agree with you, the battery indicator is the main thing I use, and yeah, that "You're on your own now Pal" when you run out of gears is amusing. For me though, the most useful feature is the ability to scroll screens with the shifter buttons. Thanks, Jon

[@oxharp]

@@ribblevalleycyclist I think it will work on the new M1 chips macs so I am told.

[@ribblevalleycyclist]

@@oxharpInteresting. I have an Apple M1 Pro chip…… I’ll let you know

[@turbotron1]

Do I need to get this module to connect the latest DI2 components?!

[@ribblevalleycyclist]

The modern 12 speed stuff has Bluetooth built in

[@amritv6889]

recently, i had left (didn't disconnect) my 2024 12 speed 105 di2 system connected with the garmin edge 830 and this resulted in draining the battery of 2024 12 speed 105 di2 system fully. This also drained the battery of the left lever. Have you experienced this type of phenomenon ? please advise... thanks!

[@robertmcfadyen9156]

How do you cope with mobile phone downloaded update patches if they are corrupted by bad signal or high bit error rates . Can the head unit resolve corrupted firmware updates ? Also , after about 200 or so updates , the operating system loses the ability to update and says unsuccessful . I saw this for the first time on a high mileage unit last weekend . DVD and Blu - ray recorders do this as well . I find Di2 rather touchy and easily upset .

[@ribblevalleycyclist]

My tip is, only update one peripheral at a time. I think there is also an argument for not doing it at all. After all, if it works okay, then why update it?

[@Raymond-Farts]

Shimano and their Will to control us did not think that we like to choose our own gearing and left out the 11-32 cassette if you have Dura-Ace 9150. 11-32 works perfectly but Shimano won't fix that in the APP. So my Garmin doesn't report the correct gears. But knowing my battery state is handy because I can't remember when the thing needs charged. For that reason I will be going back to a mechanical drivetrain on the new bike because I'm sick of charging stuff just to ride daily.

[@MagicshineLights]

Wow!!!Great!!!

[@BikeSuperfan]

My shifters are wireless, I don't think that I can fit it in the stem.

[@WowRixter]

I have a weird problem with my Garmin Edge 530 and 840 across bikes equipped with Di2. When I swap head units across a bike, when I press the Di2 button on my hood/lever, I get a message on my Garmin asking if I want to configure the device for Di2. It's already configured and I just ignore it, but have you ever come across that?

[@ribblevalleycyclist]

Hi Ric, I’ve been giving this one some thought, because I’ve never heard of it before. I can’t think what can be causing this, other than the two head units are under two separate Garmin accounts…… which I’m sure they’re not. However, I can’t imagine there are many people that are doing what you do, with them using multiple head units on Di2. It could just be that there is a glitch that Garmin isn’t aware of. Their support team is really good, it may be worth getting in touch with them on this one. Let me know if you get to the bottom of it, because I’ll be interested to know. Thanks, Jon

[@robertmcfadyen9156]

The current Di2 can only be paired with one head unit at a time to stop collusion with other units if you are riding in a peloton to stop data sharing and interference if another Di2 unit is close by .

[@WowRixter]

@@robertmcfadyen9156 that's super helpful

[@peterlip8]

Question. I installed Di2 in 2015, and there has been zero maintenance in the last 8 years. It’s stopped working, and I’m trying to connect the E-tube app to the display unit I have. Something like a SC-MT800. It’s prompting for a code to connect. Is there a default number?? Or is it something I added 8 years ago, and have to try and guess what I was thinking back then. It can see the device, so that part of it is working. Just can’t remember the connection code.

[@Sofahunden]

Another youtuber mentioned 000000 this should be default... Not sure. Give it a try. I ride di2 11speed no dfly yet

[@peterlip8]

@@Sofahunden I never worked it out what the PIN was, but I managed to fix it. I used the Di2 charger from my road bike, which plugs into a port on the SC-MT800, and connecting to an older version of E-Tube (current version doesn't work), I could change the PIN. I have a distant memory that the PIN can't start with a zero, otherwise you can't connect to it via bluetooth. Not sure if that's true, or a mis-remembered memory.

[@bobbafett1971]

So with the newest ultegrea 8100...do you need this?

[@sbccbc7471]

D-Fly connectivity is already part of the groupset inside the rear derailleur. Fourth-generation Di2 also uses a thinner wire gauge and new wire ports & connector heads.

[@Bgdutch77]

My one is not intstalled on the bike permently, plug it in when needed, do your thing and take it off again. Dont care about th compatilty with the garmin and shit, just ride! nice video do

[@ashleyhouse9690]

How are your Di2 cables routed into your stem?

[@ribblevalleycyclist]

Hi, The bike in this video has the MOST Tiger Aero 3K Di2 stem, and the MOST Jaguar XA handlebar. This allows for routing directly through the bar and into the front of the stem. The Di2 cable then appears out of the bottom of the stem where it meets the fork, and routes down to the downtube. It’s not fully internally routed, as it routes externally at the point mentioned, but it’s still a pretty tidy option. Thanks for watching. Jon

[@ashleyhouse9690]

@@ribblevalleycyclist Thanks for the explanation. I thought it would have to be a certain stem/handlebar combo which makes the solution a bit non-standard. I would imagine most people have a normal bar/stem combo which obviates this and have to put the Di2 wireless unit somewhere less than ideal.

[@ribblevalleycyclist]

To be honest, most of the bikes I’m seeing now are Di2 compatible in the bar/stem. It’s just a small hole by the lever for the cable to enter the bar, and another at the stem clamp for it to exit. It then just routes through the stem and out the bottom. As I say, a lot of cheaper bars and stems offer this. Worth taking a look at your options. Jon

[@robertmcfadyen9156]

The head unit needs larger data memory capacity .

[@ribblevalleycyclist]

Older units used to have a micro SD slot...... Maybe a better option in some applications.

I find Di2 needlessly complicated compared to Sram Axs. You even need a stupid costly tool to plug in the battery. Cables that are tool long/ short - not right one - fitting battery in non standard seat tube faff. Etap - set it and go.
