Secret Features Of Your Shimano Di2 Groupset

[@gcntech]

How do you configure your Di2 groupset? 🔋⚙️

[@akaraikiriakatsuki3157]

😂 I don't. I only have m6100 Groupset

[@FurySpyder]

Using the e-tube app! I think typical Di2 users will generally fall into two categories; those who buy their bike from the bike shop and take it back when anything goes wrong; and those who love to tinker and to their own maintenance and also maybe (like me) build their own bikes. The former group will probably never experiment with all the features in e-tube, the latter group probably will. I like to tinker with electronic gears just as much as the mechanical parts of the bike! It's always amazed me what you can actually do with Di2 that isn't really 'advertised' by Shimano, in terms of the connections and minimum components required and what will work with what! I have built some very unusual bikes with Di2 that weren't designed for it and have even spliced Di2 cables together to make a bespoke cable. It was very fiddly, because the wires are so small (and the silicone sheathing so relatively thick) but it works perfectly!

[@davidbee8178]

Nerd questions - thanks guys first of all for the fun informative video ! 1) I'm imagining that every DI2 comes with its own individual frequency in order to avoid confusion in the peloton or group rides - can you imagine ? LOL :-) . . . . 2) are the black attachments on the wire that look like tie wraps - are they antennas for the system ? Thanks and cheers from MTL !

[@FurySpyder]

​@@davidbee8178the things that look like tie wraps are very similar to tie wraps but just clip on to the wire and are designed to stop the cable from rattling inside the frame.

[@jasonree]

Love my Di2. Definitely a wow factor when I got it, wouldn’t move away from it.

[@schrodingerthecat]

Di2 is expensive but I've found it to be so worth it. The shifting is always spot-on, no need to fuss with cable tension. It's quick. There's also auto-trim on the front derailleur depending on what rear cog you are in. I also think there you should have also mentioned the synchronous shift modes. Most recently I have fallen in love with full synchronous mode, which you didn't mention here!

[@user-un6md9hh5x]

Another vote for Full Syncro mode here. 100% right hand shifting for me now. Integration with my Garmin head unit alerts when the next front ring shift is about to happen - which you do have to account for to allow both derailleurs to do their thing. It's a small inconvenience compared to the benefits of getting a linear progression up and down the gear ratios and automatically avoiding cross chaining. I don't think I'll ever ride anything but Full Synchro again. I kept the left hand buttons 'as is' just in case... 3K miles later, I literally haven't used them once. With my hood top buttons configured for page left and page right on my Garmin, I'm wondering if there's really anything I could/should configure the unused left buttons for...

[@jeffb1886]

My setup exactly (except I have a Wahoo Bolt)! 👍

[@ryoukokonpaku1575]

Free up another paddle on the right using front shift next. Meaning it'll need just 1 paddle to switch your front chainring. The extra paddle can be then used for other stuff like the new garmin 1050 bike bell or lap function. Or for gravel grx I think some dropper posts can be activated via ant+ which can be assigned to the extra paddle.

[@DmitriiKovergin]

I have the same configuration and noticed that the right hand shifting's battery is low after 5.5k while the left one is still good

[@keithreed5009]

I also use full syncroshift but use left buttons to scroll through Garmin pages, easier to use than the top butyons

[@jm892]

I’ve 2 s-works TARMAC SL6 one with mechanic Ultegra and the other with Dura-Ace Di2. Obviously the electric is much more soft and fast almost without any maintenance but the charge, the mechanic still remains a beautiful and easy to use piece of gear !… IMHO

[@darkm4g1c]

I slapped together used mountain/ road di2 with a 46/30 crankset and thought it was pretty neat. Finally got around to building up an r8000 Di2 set up and realized what I was missing when I used parts that were actually supposed to work together lol. The E-tube app is a game changer.

[@TheOkinawaBoy]

Riding third bikes with Ultegra Di2. Will never go back to mechanic shifting. I like the feeling it shift under load. So precise shifting, only one connection to charge. Lasts forever.

[@davidbee8178]

DI 2 will be on my next bike :-) The ONLY downside I've heard has nothing to do with the well developed Shimano system. It has to do with riders ! . . . feeling so confident with the long lasting batteries that they literally set and forget them only to get stuck in a gear because the batt went dead on a ride. I think if they last a year, I'll just replace them on my B Day :-) Enjoy !

[@peterthomas8053]

Another great and informative video, but, I'm going to have to watch it half a dozen times or more, to take it all in.

[@thegearboxman]

Given that my business is motorsport gearbox control then I really had no choice but to buy Di2 for one of my bikes (honest wifey!). By comparison to racing cars, bike shifting electronics is very rudimentary in terms of the technology, but the results are awesome. It's an absolute game changer, even for an old bloke like myself. Other than the speed, consistency and smoothness of the shifting, the most useful feature is being able to scroll pages on my Garmin without taking a hand off the bars.

[@ghowell13]

Oh, man! That alone may have just sold me on a DI2 setup. Ideally, I need to figure out doing it on my 2011 Madone. I would love to add the chaging port to the handlebar end, too. End resulting problem is that I need rim brakes, though. And as Alex recently found, you can't do that.

[@billeterk]

I wish Exposure went with ANT+ instead of their own BT protocol. It would be good to have high beam on the hidden buttons :-)

[@robertmcfadyen9156]

Voice control is already here with one setup I have seen .

[@robertmcfadyen9156]

​​@@billeterkThe derailleur has a sensor in it . This enables the 50 metres range . The danger is that if you pair your derailleur with someone else's , it can mean controlling it from another bicycles cockpit . I have seen this happen . A spectrum analyser shows that Shimano etube has a hidden lie . It uses infra red signals .

[@JulAlxAU]

You forgot connecting derailleurs to the head unit. Di2 can be connected to the head unit to display the gear you are riding in. Very nifty to avoid cross chaining.

[@davidbee8178]

As far as I know, if properly set up, DI2 helps you avoid cross chaining

Very interesting info as someone who just got modern Di2. To see how the sausage is made so to speak.

Awesome video,i can't believe how advanced Shimano were with Nexave but Dura-Ace is still the best.💯👌🏻✌🏻🚴‍♂️

[@riteshgarg]

I use Ultegra Hydro mechanical groupset and I feel the shifts on that are faster, I can even shift 2 gears down in one go. I have seen my friends struggling with the DI2 when it goes to crash mode after bunny hopping or loose power because they forgot to charge. Till now I didnt understand the real use of it

[@uknowbass]

Eye blink is between 80 and 110 milliseconds unless you had a blepharoplasty then it’s slower like 150 ms

[@junjakoti]

Do you think that extended range leaves the bike venerable to wireless attack?

[@nstewart9964]

Very cool tech. I am still riding around on 2x10 Ultegra 6700 DI2m early tech

[@_J.F_]

I have got the 105 Di2 so only 4 buttons available. I have decided to embrace the technology though and run full synchronised shifting meaning that I only need my right hand shifters to shift up or down (long hold shifts 3 gears) and I don't need to 'worry' about the front derailleur as that is done automatically. It is fully customisable so I don't see why you should not set it up to suit your needs and then leave the the tech to do the work for you. This means that I have both buttons on the left hand shifter available to control my head unit, or whatever else equipment you might want to operate with a quick click of a button on the go. I do of course see the benefit of the buttons in the hood on the more expensive shifters but until I win the lottery my 'poor man's' version will have to do 😊

[@marcelmarkov3500]

[@papermasta123]

[@bikeanddogtripsvirtualcycling]

have never used di2 before, however I am hoping to get a new bike (some time next year - thinking Cinelli pressure) and then in spring 2026 I am currently planning my first cycle holiday (actually first holiday since 2007). Plan is to make my way to Rome by train then cycle up the west coast of Italy before taking a left to visit San Remo and Monaco and then kind of taking a diagonal through France in to Belgium, take the Ferry over to GB and then cycle up to Liverpool. My concern is that the bike I want comes with 105 DI2 and I obviously don't want it to run out of power. Would I be best getting a spare battery at the time or if I am on a long flat stretch of road would it make sense to put the bike in to a sensible gear and then just unplug the battery for however long. There is a lot to think about. need to renew my passport too as it expired in 2012

[@TerjeMathisen]

I got my Di2 bike back in 2014, almost by accident (did not know what it was!). This was the original wired version, on a Cube carbon bike with internal wires so it only needs a single battery. Seems like not having a wireless network is a security feature today. 🙂

[@rommelreyes2209]

[@notpablo8369]

id lubricate your smooth brain

[@jeffb1886]

My only complaint with my Ultegra set up is that I just can't seem to find a smooth "sweet spot" of rear downshifting when the chainring moves from the large ring down to the small. I've reviewed gear ratio tables for my setup and a 2 gear shift "up" in the rear to compensate is the right gear ratio adjustment. But a 2 gear shift is slow, chattery, and prone to pedal skipping just when I'm starting my climb. A 1 gear shift up on the rear is smoother but too much of a "hamster wheel" jump on my legs. (Going the other direction from small chainring to large and a compensating 1 gear downshift in the rear is smooth and hardly noticeable.) After much testing of different downshifting combinations, I've resigned myself to just "living with it". I've setup my Wahoo Bolt to show gear positions so at least I know when my next "clicK" will do it. :-(

[@emaneliforp7875]

I have just had to figure out why my Di2 suddenly started having intermittent issues whereby it would stop working for a few seconds then work again for a few seconds. This was a nightmare. But an even bigger nightmare was the immoral costs of parts. Even the cost of the wires is scandalous. A new battery.....I think was £140 I paid. Thankfully, I didn't need either new derailleurs or shifters. I have throughly loved it until I needed new parts.

#askgcntech Hi Alex and Ollie, is there any way to connect wireless extra buttons to shimano Di2 12s without any cabling? Sram is already doing it with their blips.

[@sbccbc7471]

No.

[@cm.5023]

So, they can further improve battery life by reducing the transmit power, since no one needs to be that far away to shift.

[@jordanbell4331]

Incredible video. So good actually that I ran straight to my bike (with 105 di2) and attempted to set up the Front Shift Next function on my left shifter, but that option is not there! :'( It doesn't seem the app needs an update, and my firmware is up to date. Any one else not have this option?

[@PiotrJarolewski]

Please make the same test for Sram AXS :)

[@wesleymason-h1m]

how does DI2 pick out your DI2 from a peleton of say 180 riders

[@daztastic147]

The benefit is it’s electronic, bringing accuracy, smoothness, speed etc, but there’s no need for it to be wireless. The components are permanently on the bike, they’re not removed and replaced on every ride, so it may as well be wired, you then have all the benefits, but no risk of interference or hacking. It can still have wireless Bluetooth connectivity for app control, but absolutely doesn’t need to be wireless between the shifter and derailleur.

[@oliverjacobs8594]

Fully wireless does make internal cable routing easier, but certainly has its disadvantages too as you've mentioned.

[@CnyMTB]

Until something doesn't work and your nor sure if it's junction box a, junction box b, left shifter, right shifter, battery, front derailleur, rear derailleur, cable from battery to junction b, cable from junction b to rear derailleur, cable from junction b to front derailleur, cable from junction a to junction b, cable from junction a to left shifter, cable from junction a to right shifter, or cable from left shifter to right shifter. 🥱 that sounds like a lot. Some can have another wire or 2 and another junction or accessories. Sure is a lot

[@joshaalders3029]

Let’s be honest Leroy, you are an absolute weirdo and we love it!

[@jefffixesit60]

I love that this technology exists, but 99% of cyclists don’t need or want it. I will continue to limp along with my cable-operated mechanical shifters and derailleurs, triple chainrings, and cassettes that cost less than $70 to replace, while racking up 5K miles per year and never having to replace batteries. The amount of functional 105, Ultegra, and Dura Ace components I can purchase from the used market, in 9, 10, and 11 speeds, should keep me cycling happily along for at least another decade… by which time I’ll be 80 years young!

Do you need top of the line electronic shifting ? Same question for buying a Sports car vs an Econo - because the smile it gives you, or not

No need. You have synchro shift…and 6buttons (even Sram realised having only 2 buttons is too few)

[@keeferification]

This is great and all, except for the fact Shimano neutered the Hammerhead Karoo for... reasons? Glad I spent 4 grand on 9200

[@eddysobieralski8075]

If it's a Karoo 2, that's easy to solve - you just need to side-load the KI2 app on the Karoo 2 to restore the functionality. It was a 'competitor' thing driven by Shimano which caused this when SRAM bought out Karoo - they told them to remove the code.

[@ОдессаВелопланета]

haviing r7170 groupset 12 speed di2 charge battery every 500-900km The more i ride long distans the longer battery lives Which means 2-4 times a months, not an avery few month

[@drill_fiend1097]

The biggest party pooper of di2 is that the shifters need $400 special cable to update firmware, and that's separate from derailleurs which can be updated through phone app. These are kind of inconsistencies that make me realize Japanese companies are always behind in terms of software... But again still prefer shimano FD and brakes over SRAM.

[@DryhumorGuy-1]

I used the e-tube app for my older 11 speed for the first time last night. I used the wireless setup. I imagine that you are talking about the newer Dura- Ace as he is in the video? Why do you need that cable to be able to get into your shifters instead of wireless? I could have went derailleur, power m., junction, or shifters. Also, I just got a 12 spd SRAM as well. I will be learning about that, but why do you say Shimano over Sram? Thank you....

[@MrSJR39]

This sounds so complicated. Love my mechanical cable gears!

[@whitebear96]

the need to have separate battery in the seat tube which must be connected by cable to both shifter and mech is complete turn off for any electronic groupset from shimano.

[@dorohmc]

Having test ridden a bike twice with Di2, I opted for mechanical in the end. Although shifts were fast, I felt disconnected from the bike. Saving more than 1000 euros based on the groupset alone, I put this money toward upgrading wheels and would make the same decision. I recently came upon cyclists in FurkaPass in Switzerland who had a beautiful Pinarello fitted with Di2. However, major problem - he could not shift either deraileur and claimed he charged system by night before. Not the place to have this type of problem and further confirmed my buying decision. Cheers to those who want more tech , expense and complexity to their cycling experience.

[@izi941]

Just like your gear cable can snap, a Di2 can fail too (the guy was probably leaning his bike on the leaver, pushing the buttons, draining the battery over night…happens way too often). Altho, Di2 maintenance is much easier than maintaining mechanical groupset, especially in wet/muddy weather

[@billeterk]

Mechanical is pretty good. The advantages of di2 for me are easier with small weak hands and slightly better when you need to quickly brake and shift simultaneously.

[@michaelz7190]

This reminds me of my new humidifier. It replaced the old one that had 3 setting and on/off button. The new one has the same controls only to set it up you need download the app first. It also has touch control display that never works from the first touch, only after many tried. I recently looked at new cars to replace my 10years old Accord. You need to take a course to know all useless bells and whistles that car has and 99 % are totally useless. Electronic gear shifting is terrific tool to extract money from clueless customers and unless you are Cav type sprinter who’s income may depends on speed of shifting gears, Di2 or anything similar reminds me of my new humidifier. Tech for the sake of tech. Makes no sense.

⁠@@joelnace1793only with wireless protocol updates (“bluetooth” module update) need wires. No need fo expensive tools, just plug the FD cable to the STI and update it…or let the workshop do it at your next service (in EU, by low, they aren’t allowed to charge you for updating)

I wonder if its possible to hijack the signal and shift someone else's bike.

[@andreasolsson2336]

~~ Do i need this technology - NO- do I want this technology YES - A paid advertisement video !!! All these features are found in the new Chinese Electronic shifting, at a fraction of the price !!!!

I just downgraded to friction mechanical shifters. I can now shift the entire width of the cassette in 0.4 seconds and go on holiday with the money I saved.

love this! but, please, your one-man-camera guy who thinks he can do all: rather stand still with the cam and adjust the brightness of the image, instead of doing inconsistent moves with a crapy gimbal. the host is enough. he has it. all. content and presence. if u wanna do camera - go to hollywood. this is a 'content king' channel.

Know it now uses wifi and BT as the hacking scanners can attack it using wifi,the far distance control from its high speed 5ghz wireless coms gives thes hackers plenty of range to play with, if they done like sram and used the close range high speed 2.4ghz it would have to be 10ft from the bike to work it would be almost impossible

Prefer SRAM
