Cool but not useful:
- Being able to visually see what gear you are in on your computer.
They (Shimano) recently updated the iPhone app. I haven't dug into it yet so do not know if there are any new functionality. Maybe someone who has dug into it can confirm.
So this Shimano thing let's you swap pages in your bike computer by pressing the shifters instead of actually having to touch the bike computer? Without it you cannot update the software (and is this actually needed for electronic shifting?)? And what is the gear assignment?
