Robusta converted to DI2.

FSA Gossamer crankset with FSA Fr Der hanger.

Removed the inner ring, installed both BB spacers to left side to position DI2 Der correctly. Works great as a standard 53/39 setup.

FYI, we wanted a "compact" setup for the summer as we train for Leadville, which will involve lots more climbing. I moved the spacers back to standard (one each side). Then installed a 50t ring on the INNER 130mm BCD position, and a 34t on the 74mm BCD position. Installed a standard Shimano Fr Der hanger (moved der back inboard to standard). Works great as well.
