Di2 provides precise and coordinated front shifting to SHIMANO 105

SHIMANO Di2 electronic shifting allows you to switch from large to small chainrings, or vice versa, whenever you want, minimizing the risk of chain slipping. Likewise, you can make rear shifts without having to adjust the derailleur to avoid chain friction. Full and semi-shift functions can be selected via the E-TUBE app. With precision digital electronic shifting and coordinated communication between derailleurs and derailleurs, the new SHIMANO 105 front derailleur offers the best shifting you've ever experienced.

• Powerful, precise and smooth front shifting
