Shimano Derailleur Ultegra Di2 FD-R8050

The new FD-R8050 has been redesigned so that it can accommodate wider pace chains without sacrificing gear performance. A rapid and fluid front change is guaranteed in all circumstances, even when the chain on the external crown moves and get up from the saddle. Initially introduced with the XTR DI2 M9050 group, the innovative Synchro Shift Tecnolgia is now available on Ultegra R8050. This is an Di2 programmable function that creates an intuitive experience on the bicycle through the synchronization of the front derailler and the rear gearbox, which can be programmed directly by the user. In addition to the "Full Synchro" function, it is also possible to use a "semi synchro" function: this is a new mode that automatically reacts when the cyclist goes from one crown to another, also changin.
