Shimano 105 Di2 R7150 2x12V Front Derailleur

The Shimano 105 Di2 R7150 2x12V front derailleur allows you to switch from the large chainrings to the small chainrings, or vice versa, whenever you want, minimising the risk of chain slippage. Similarly, you can make rear derailleur shifts without adjusting the derailleur to avoid chain rubbing. Full and semi-synchronised shift functions can be selected via the E-TUBE application. With digital precision electronic shifting and coordinated communication between shifters and derailleurs, the new Shimano 105 front derailleur offers the best shifting you've ever experienced.
