The Shimano 105 Di2 FD-R7150 2 x 12-speed front derailleur offers precise and coordinated shifting. The electronic shifting of the SHIMANO Di2 system facilitates shifting from the large to the small chainring and vice versa and reduces the risk of a chain jumping off. In addition, rear shifting no longer requires re-trimming at the front derailleur to prevent the chain from dragging.
