I exchanged a few emails with Wahoo, but nothing ever came out of it.

At the time, having road shifters was locking the system in 2x mode. This may have changed since then.
In my case, I have a Deore XT rear derailleur with Ultegra road shifters. E-tube was perfectly fine with it but not the Wahoo unit. I gave up.
