If you have a bike with a BB30 and wish to convert it to electronic shifting, you have several options: you can change to Shimano by either using a BB adapter or changing the BB to one that converts to the Shimano crankset or you can do the same if you wish to convert to Campagnolo. However, the best option is to convert to Sram e-Tap as Sram makes both GXP and BB30 cranksets in e-Tap livery. The e-Tap is a very simple installation and will neatly fit any bicycle, even those made for external cables, and it works marvelously.
