Has anyone figured out a good way to fine tune the rear derailleur on an eTap aero set up? the instructions on the manual seem to say you need both hands on the controls, so you can't really pedal at the same time. making it hard to hear the subtle differences between button pushes. I suppose I could find a helper to pedal for me while I make the adjustments... eTap is starting to become more prevalent with TT/Tri crowd. Just wondering if anyone figured out a shortcut. Thanks in advance.
