E-TUBE PROJECT Cyclist 4+

Difficult to connect: sometimes it connects easily, sometimes it doesn’t. Plus it’s only one button on the derailleurs so if you struggle to connect and push it repeatedly, you can accidentally change modes. Also the most prominent thing should be battery health. It’s also just 5 simple green bars for the derailleurs and a single green light for the shifters.
And passing along a warning: my LBS made it very clear to not try updating via the app. They get back bricked bikes all the time from people trying.

The old version ‘bricked’ my old ultegra the first time I used it 3 years ago when I got a new bike 😵‍💫 fast forward to 2023, and my new 12 speed Dura ace updates flawlessly, as do adjustments with the bluetooth connection - just gotta go slow, read the instructions, keep phone near to components. BUT please update the wireless shifters without a wire connection (which I don’t have). Also why only PC software? I have to imagine lots of folks with more advanced groupsets are Mac users exclusively — watch GCN. That said the mobile app on iPhone works, but one definitely worries every time one updates, if this will be the moment it crashes - QA

As most reviewers have said there are several possible problems with using this app. If you do your homework, that is read all the negative reviews and watch the you tube videos you can skip all the headaches. I’m not the most tech savvy guy, but after reading all the feedback I didn’t have a single problem getting everything to work as advertised. As mentioned in other reviews install the EW-WU111 and then up date all the firmware through the battery charger connected to a PC with E-Tube installed. Then I used the E tube app on my IPhone to customize everything. When done with the app be sure and disconnect it from Bluetooth and you will be good to go
