Why We Like The Di2 Inline Wireless Unit

The Shimano Di2 EW-WU111 Inline Wireless Unit boosts the system's ease of use by adding Bluetooth connectivity in addition to carrying over ANT+ to pair with an even wider range of devices. Paired with Shimano's E-Tube Project Wireless app, the Inline Wireless Unit lets you customize your drivetrain and update firmware right from your smartphone or other Bluetooth equipped device.


This diminutive component is like a black box for your bike, feeding data from your derailleurs to your phone or tablet so you can monitor drivetrain metrics like gearing and battery life. The latter is especially useful, as it's looking to be the most effective way the industry has come up with to ensure you won't unexpectedly run out of juice during the trip home. It also measures general riding metrics, so you're not sacrificing the functionality of a normal computer by adding drivetrain info to your cockpit. Your pedal revolutions will also be televised.


The Di2 EW-WUlll Inline Wireless Unit is compatible with Shimano's E-tube Di2 systems. In addition to its Bluetooth connectivity, it transmits via ANT+ to Shimano's own PRO computer, as well as other ANT+ equipped head units.

No problems for me

Familiarity:
I've put it through the wringer

I bought this with trepidation because of the other reviews but had no real issues. Yes, Make sure to update everything before you start Then choose it at a sensor on your wahoo or whatever and you'll be able to see your gears, know how much charge you have left and switch screens with the buttons on top of your hoods. Worth $70? Your call.

Handy Tool

Familiarity:
I've put it through the wringer

I'll start by saying I've had some of the same frustrations as other reviewers, but I've found some tips to help make things go well. First, ensure your phone is charged and that no further updates to it will happen while using the E-Tube software. Next, ensure that the software is up to date before any firmware updates. And lastly, don't be in a rush, be patient while using the software. Sometimes it can take a while and appear to stop working when it is actually thinking in the background. If you take that care you should be good. FWIW I am using an Android phone and that may help (everything Apple seems to think it is smarter than everything else and tries to control the situation and tends to muck things up). All this said and done, the hardware works and can make updating firmware on your drivetrain pretty easy.

Prepare for brain damage

Familiarity:
I've used it several times

Physically installing this unit took all of 3 min (and another Shimano cable not included). Getting the unit connected to the Shimano E-Tube app took 2 hours, multiple devices, and a lot of swearing. Connected to my iPhone on first try but would not run firmware update. Installed E-Tube app on PC and updated firmware. Once updated, unit would not connect to iPhone no matter what I did. Ultimately ran through several additional Apple devices before my daughter’s iPad finally connected and finished setup. It was mind numbing and I nearly gave up. The unit now works great. I really like seeing gears on my Wahoo screen and controlling the pages/zoom. Knocked stars off for terrible setup but once setup completed, this works as advertised.

The Bluetooth connection was interrupted during a update, and now it's completely dead.

Risky to use

Familiarity:
I've used it once or twice and have initial impressions

The problem with this unit is that if anything goes wrong while you're using it, it can lock up your system to the point that you can't shift and you can't recover without the help of a bike shop - at least officially. Unofficially, there's a messy hack you can do (but I won't go into that). My experience was that my IPhone went into power-save mode - as it often does - during a firmware update, and it totally locked everything up. My recommendation is to download the e-tube software to your PC, and do all of your updates and customizations that way. There's much less chance of a disconnect, and it's much safer.
