Hello All,
My Dura - Ace left lever has a malfunction. When my Garmin 1040 is powered on the left lever doesn't work properly just after so many clicks. It seems to not connected to the rear derailleur which is the brain of the system. Surly it's a connectivity issue what causes the Garmin headunit. Because when it's powered off everything is working good.
Is someone facing the same problem? Even on lower model series like Ultegra or 105?
Thanks for the answers!
