The patient is 2019 Cannondale Synapse with FSA crankset, BB30. I have an issue with adjusting the front derailleur. The chain rubs against the derailleur cage but only during the push phase of the pedal stroke. I recorded a video to get a better look at the issue and I noticed that the crank slight moves once the pressure is put on the crank. On the video you can see that when I clip in and when I push during the pedal stroke the crank moves slightly to the outside.
Is there a way of correcting that?
