Description

Increased connections.

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 it Bluetooth connectivity, it transmits via ANT+ to Shimano's own PRO computer, as well as other ANT+ equipped head units.

  • Shimano's wireless unit gets upgraded with Bluetooth connectivity
  • Communicates with devices with ANT+ and Bluetooth protocol
  • Wirelessly customize your drivetrain with the E-Tube Project Wireless app

clean install-great for training

    It's one of those things you can live without but once you have it on your bike you can't live without it. Installed the wireless unit inside the bike using the access panel under the crank. Not recommended by Shimano but I got a strong signal to my cpu and phone. Love being able to log intervals from the hoods of my shifters. Can update firmware of all DI2 components with my phone. If your tech get one...

    Great way to update and configure Di2

    • Familiarity: I've used it several times

    I bought this to update and configure my Di2 systeem with my iPhone since I don’t have a computer. I plugged it inline with the main wire from the junction A box and an extra 150mm wire and then used the included clips to secure it to my brakeline. It connected just fine to my iPhone right from the box, and I was then able to update and configure all of my Di2 components.

    Connecting it to my Garmin head unit is a nice feature so I can see the battery level. Being able to see what front and rear gears I am in is a nice feature, but I don’t use that feature on my head unit.

    Almost threw it away

    • Familiarity: I've used it several times

    Make sure you install this thing pretty immediately; it's about the size of a bottle cage bolt and we mistakenly threw it away because it was hard to tell if it was even still in the packaging.

    Indeed, after a simple firmware update it all works well.

    Hi, Do i need a different battery if I have the latest Durace Di2? or just buy this unit, install it, and go? Thanks

    I am installing Di2 9150 with the DN-110 battery. Where should I install this inline wireless transmitter?

    HI Seth,

    You will want to use the WU111 transmitter inline on the "main" wire that runs from the center port in the "A" junction into your frame. You will need an additional E-Tube wire to go from the A junction to the transmitter, then the main E-Tube wire plugs into the other end of the transmitter and continues to the B junction. The transmitter includes clips to attach the transmitter to the brake cable housing to keep it secure.

    Feel free to ask me any Di2 questions you might have or let me know if I can help with anything else.

    Be sure to update firmware!

    • Familiarity: I've used it several times

    The unit works great, but shimano has been shipping a lot of these with a very base level firmware installed that will not let you sync to bluetooth until you plug the system into a computer and update. Once that is done, it syncs perfectly to a smartphone and lets you do firmware updates and Di2 customization from the phone. Also connects to certain head units and will show you current gear you are in and battery level.

    Will this unit allow you to update your firmware?

    Do you know if this product works with Ultegra Di2 11-speed? Thank you.

    Yes it will but you will need the new internal battery, BT-DN110. If you have an external battery then you will need the new external battery mount. Without these, it will crash your system. Hope this helps! Let me know if you have any other questions, you can reach out to me directly!

    I just got off the phone Shimano tech support. I have a 2014 Kestrel w/ Ultegra Di2 11-speed with the battery mounted on the down tube, below the water bottle holder. According to "Randy", you need this, along with the Shimano BM-DN100-S Bluetooth Di2 Battery Mount. I'll update after I receive the parts.

    Thank you all. I ordered the new battery and will know more tomorrow night. I hope it is very plug and play with just the new battery.
