SHIMANO 105 R7150 12-speed front derailleur

SHIMANO Di2 electronic shifting lets you switch from large to small chainrings, or vice versa, whenever you want, while minimizing the chance of chain skipping. Likewise, you can make rear shifts without having to readjust the position of the front derailleur to avoid chain friction. Synchronized and semi-synchronized shift functions can be selected using the E-TUBE app. With digital precision electronic shifting and coordinated communication between shifters and derailleurs, the new SHIMANO 105 front derailleur delivers the best shifting you've ever experienced.
