You can just swap out the driver on DT wheels.

@dubtap

no compatability with old etap

to be expected, just like the first di2 groupset.

There was no backwards compatibility with di2 because it used different electric signals, etap is using the same Aria wireless system

I don't think it's that simple, an apple TV and Android phone both use Wifi, yet they can't talk to each other.

I'm sure they found some issues in the protocols used in last few years and changed it a bit.

BTW in etap 11s specs it's called airea and in 12s specs it's called aria.. Kinda weird.
