How to adjust the button configuration on a bike with SHIMANO Di2?

You can adjust the settings of the left SHIMANO Di2 shifter in the Classified Cycling app. Adjusting the shifter settings in the SHIMANO E-tube app is not possible for the left shifter. The shifter settings of the right SHIMANO shifter, that operates the rear derailleur, need to be changed in the SHIMANO E-tube app.

To change the settings on the left SHIMANO shifter, follow the below steps:

1. Open the Classified Cycling app
2. Go to 'My bikes'
3. Select 'customize'
4. Choose your shifter setting.
   1. Toggle mode: each press on both L1 and L2 of the SHIMANO shifter generates a shift.
   2. Reverse up and down shift: swaps the funtionality of the two buttons on the left SHIMANO shifter. Up becomes down and down becomes up.
