By default, Shimano Di2 drop bar shifters rely on the right shifter to perform the shifting duties of the rear derailleur. In a 2x system, this places a lot of wear and tear on the right shifter, while the left shifter sees much less use. In this video, JOM of the Gravel Cyclist crew explains how he splits the shifting duties of the rear derailleur between both shifters, evening out the wear and extending the life of your Di2 system.
