Provides a much needed wireless connection to your 11sp Di2 setup
The WU111 is very easy to install, simply connect one end somewhere inline with your Di2 system. It can either be installed as the last item in a chain or as a connector between two wires.Has worked flawlessly every time so far on two different systems. Note this is for 11sp Di2 as 12sp has wireless natively. The two systems are not interchangeable. It also requires the newer 11sp battery and will not work with the old battery.If you want to or need to update firmware, change settings or perform other maintenance on your 11sp system, this allows you to connect to eTube from your phone and replaces the annoying method of connecting a windows PC.

Works well, easy to install
Not sure why this didn’t come with the bike in the first place, but hey…. Shimano gonna Shimano. Really easy to instal on my bike, since there was a “pass through” adapter that could just be replaced with this unit. Works great.

If you are using di2, I highly recommend it!!!
The wireless plug for my di2 system has changed how I use my bike, and it is the best upgrade I've done next to the electronic shifting. The ability to log into an app and adjust the gearing on the fly is amazing.

Was very easy to install.
I’m very happy to be able to connect my bike to my phone and it is nice having the gears on my computer.

It’s really small. I was able to rout internally within the handle bars.

Bluetooth stays on and runs down Di2 Battery
It took 2 attempts to get the device updated via the E-Tube app but finally held and all functions seem to be working. Problem is the D-Fly Bluetooth transmitter never goes to sleep - stays on 24/7 even with bike sitting idle. The result is the battery drains about 10% every day without any shifting going on. The app is disconnected from bike and closed on phone along with Bluetooth. The Garmin 530 which is paired is also powered down when not in use. Assuming a hardware defect since firmware reports up to date on ETube.Update 12/13/23 After making a wired connection to a PC running E-Tube and disconnecting the bluetooth function on the D-Fly is not staying on continuously any longer.
