How to Install the Latest Shimano Wireless Di2 D-Fly (EW-WU111) in Seat Post

Hi, very helpful video. Does it matter which battery you have in your seat post? Thanks, Bernard

Great video.

I don’t have a seat post battery. I have a SM-EW90A battery that straps under the handle bar. Would this work for me?

hello,what's the difference between the wu111 module and the wu101......thanks

Very good!

Hi, thanks for the video.

So, you didn't connect your module to the Shimano app and it still worked with the Garmin unit?

Does that mean that you do not "have to" connect to the Shimano app?

the video image is too poor, you need to fix it more

If you decide to wrap the module highly recommend Teflon. Teflon is the closest thing to air in terms of being invisible to RF ie. The Bluetooth signal. Styrofoam is ok. DO NOT use nylon, metal, or even wood. As they absorb RF. To test a material put some in a microwave oven. If it gets warm, don't use it.

BTW it won't work in a metal seatpost, or metal seat tube

Does that unit and the cables rattle inside your bike?

I have an issue on the Battery drain.
I charge it once per week!

Seeing which gear u are in - is that basically the only (or the best) reason you need dfly for?
I don want other hassles than that to be honest. My hood doesnt have that extra control on hood.
Id be really thankful for reply.

Which Shimano group do you have on your bike?

Foi muito importante para mim.

Hi , what cable you need for the module or it’s only one you can buy ?

Learn from some of my past mistakes: 1) when reinstalling the saddle, double check that the wire didn't loop into the expansion slot of the seat tube 2) I would not button everything back up before testing that it was connecting to the head unit 3) do your Di2 firmware updates before performing the installation.
