I ride with a large group where three of the riders have e-tap equipped bikes. Every single one has had multiple issues with the rear derailleur. Having said that, I will consider the new upcoming 12-speed e-tap expected to be introduced in early 2019. I assume, and hope, they have addressed the issue.
