Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Di2 Wireless module (WU111)...is it needed for E-tube app/what can you do without it?

I am getting a new bike with Dura-Ace R9150 Di2. My question is this...is there any programmability etc. without the wireless module? or is the WU111 unit required as an aftermarket purchase to use any of the non-standard functionality. As a soon to be new user to Di2, it seems a bit surprising given the price and fact that most everyone has connected devices these days that the wireless module isn't just included out of the box with a D12 setup.

In terms of programming the system, the charging unit that will be furnished with the bike (SM-BCR2) will allow for connection to a PC (no eTube app for Mac OS) using a USB to micro-usb cable and will provide the same functionality. The wireless unit is only required if you want to do the programming from a phone or tablet.

If you want to connect Di2 to your head unit, you will need the module. I agree that it is ridiculous to charge extra for it, but if you look at the overall cost of the bike (especially with Dura Ace), it's not a huge add on. I'm not sure what functionality you get with a Wahoo, but with my Garmin, I can use the hood buttons to control various functions including scrolling, lap button, light functions, etc. It's not perfect, but I'm glad I got it. The shop where I bought my bike priced it at a pretty good discount with the initial set up. I'm glad I did it.

Get the bt module. It's a small additional expense and gives some nice functionality, which you can read about on the 'net.
