I just got a new bike last Friday, and it has Campagnolo EPS components. When I added it as a Sensor, the Edge 1040 offered me a data screen for shifting status. I specified six data fields, and it all seems to work. The screen shows battery status, and the gears I'm using in several combinations - gear ratio, actual gears (like 34-19), which chain ring I'm in, 1 / 2, which gear I'm in on the cassette, 5 / 12, a graph of the cassette highlighting the current gear. etc.
Since the battery is supposed to last a some thousands of kilometers, and there's a button to make battery status display on the handlebar end, does anyone use the battery status on the Edge screen? Is there any utility to having a display other than the gears in use? Should I bother with a separate data screen, or just add a data field to an existing screen?
I believe the EPS display must be similar or identical to what's available for Di2 and AXS. (Is this true?) What do you display for electronic shifting?
