Shimano Ultegra Di2 Software

What does Di2 mean?Di2 stands for “Digital Integrated Intelligence” – Shimano’s version of electronic shifting. DI2 gives you instant, accurate, lighting-fast shifts the first and every time, at the push of a button.

Even in the most extreme conditions, shifting is precise and controlled. You can change gear even under heavy load while climbing or accelerating. With DI2, you are in complete control.Di2 is available on road bikes, mountain bikes, e-bikes and since 2019, gravel bikes.

How often do I charge my bike? And how?A is said to last between 2500 and 5000 kilometers. This depends a bit on how often you shift and also your shifting style. The front derailleur has to work harder than the rear derailleur and thus also consumes more energy. This means that if you use the front derailleur a lot your battery will run out a bit quicker – don’t let this stop you from using the front derailleur though.

It takes most people months to ride 2500-5000km and most Di2 users don’t charge their bikes more than three times a year.Once the battery level reaches 10% the front derailleur will stop working. This way the most battery-hungry operations are disabled and you should be able to finish your ride using just the rear derailleur.So? If you’ve got the or a mountain bike with a – just look at your Wahoo/Garmin or the display.Don’t have either of those? Just press and hold any of your shifter buttons for half a second.

The left LED on your junction box will illuminate to indicate the charge left in the battery. Shimano recommend charging the battery when the level gets below 25%. These numbers are an approximation.

In our experience the ranges are 100% – 75% (2s green), 75% – 50% (5x blinking green),50% – 25% (2s red), 25% to 0% (5x blinking red) How do I charge the battery?First, unpack that! One end of it plugs into your bike, the other (USB) end goes into either a laptop or an AC adapter with USB port (mobile phone charger adapter for example). The order in which you plug your devices in does not matter. Just connect the bike to the charger and leave it in until the orange charging indicator switches off – this can take up to 1.5 – 3 hours.Can’t find the charging port? Its location depends on your bike configuration. If your bike has an internal battery you’ll have to plug the charger into the junction box – either below the stem/handlebar or integrated into the frame. It has a little cover that you can open using a screwdriver or knife.Does your bike use an external battery?

Then your charger will most likely plug directly into the battery. Have a look at the image below for some example charging port locations. Important: Shimano recommend you use an AC adapter with a voltage of 5.0 Vdc and with a current equal to or higher than 1.0 Adc. If you use an adapter with a current lower than 1.0A it may “ heat up, potentially causing a fire, smoke, overheating, destruction, electric shock, or burns“.

Also, it could result in a poorly charged battery.If you have to use a computer or laptop to charge your bike, use a USB 3 port (usually blue) if you’ve got one – the (maximum) current on USB 3 ports is higher and it’ll charge quicker. What does the button on the Junction box do? EW-RS910 on the left, SM-EW90 below-the-stem on the rightBoth the current and the previous generation Di2 have a button on the Junction box.

Depending on what battery you use, the button does different things. If you use it combined with one of the old batteries (external SM-BMR1, SM-BMR2, or internal ) it:. Enters adjustment mode if you press-and-hold the button for 0.5 seconds. Enter rear derailleur crash protection reset mode if you press-and-hold the button for 3 secondsThe modern Di2 batteries allow you to enter Bluetooth LE connection mode.

Note that this Bluetooth connection only works if you have a on your bike. With a BT-DN110 or BM-DN100 battery installed:. Press-and-hold the button for 0.5 seconds to enter Bluetooth LE connection mode. Press-and-hold the button for 2 seconds or more to enter adjustment mode.

Press-and-hold the button for 5 seconds or more to trigger rear derailleur crash protection resetAlso, if you have a synchro-shift enabled bike, pressing the button twice will let you switch shift modes.Depending on what mode you’re in different lights come on. What do those lights mean? When you check your battery level different lights come on depending on the charge levels:. Green for two seconds: 100% battery. Blinking green five times: 75% – 50% battery. Red for two seconds: 50% – 25% battery. Blinking red five times: 25% – 0% charge leftModern Di2 builds will switch on additional lights right after displaying the battery status.

These show you the currently selected shift mode:. Green and red lit for two seconds: manual shift mode. Green and red blinking two times: shift mode 1. Green and red blinking three times: shift mode 2Pressing the button can trigger other modes, as described above. The corresponding lights are:.

Bluetooth LE connection mode: green and red flashing in alternating order (15 seconds). Rear derailleur crash protection reset: blinking red and red fully litShift modes / Synchronized shiftingAll Di2 builds that use the modern BT-DN110 battery support different shift modes and synchro-shifting. This means the system will switch the rear derailleur when you change chainring, or shifts the front derailleur automatically when you shift the cassette to a certain sprocket.We’ve written posts on synchronized shifting before: and, so feel free to read those if you want to know more about synchronized shifting. There are buttons on top of the shifter hoods?If you have a current generation road or gravel Di2 system press the top of your shifters and you’ll see there’s a button on top of each shifter. The series that have these buttons are: Ultegra R8050/R8070, DURA-ACE R9150 and GRX.

Do you have and older generation bike but want to have buttons on the shifters? You probably can – have a look at the and see whether your system is compatible.

Even if you do have the buttons, they probably don’t do anything. They are set up to control your Wahoo/Garmin by default, even if you don’t have an.

You can use the to change the button functionality. Should I take special care washing my bike?When it comes to washing your bike don’t worry about the Di2 components.

Your bike won’t electrocute you when riding in torrential rains and it also won’t explode if you get it wet washing your bike.Just like you would with a mechanically shifted bike, use water and soap or any other cleaner. Using a garden hose is fine, but high-pressure washing your hubs or bearings is not encouraged. How do I safely transport my bike?Not much can go wrong transporting your bike. The only thing you should keep in mind is that a Di2 derailleur will try to shift and keep trying when a shifter button is pressed. This means that if you puts your bike in the back of your car you should take care that your bike is not trying to shift all the way to your destination – that would mean getting there with an empty battery. Speaking of empty batteries – it’s a good idea to bring your charger with you, even if you just charged your battery.
