SHIMANO 105 Di2 front derailleur FD-R7150 | 2x 12-speed
The wait is finally over. Finally, Shimano's road bike groupset for the ambitious hobby cyclist comes with modern Di2 technology and 12-speed drive. And all this at an unbelievably low price-performance ratio. Nevertheless, no compromises were made in terms of durability and functionality and the many years of experience of the Japanese can be seen in every detail.
Technically, the new 105 group is similar to its big sisters Dura-Ace and Ultegra. The shift commands are transmitted wirelessly to the derailleur and rear derailleur. The latter are connected to a central battery, which can, for example, be installed well hidden in the seat post. The 12-speed drive was also adopted and allows for a larger gear ratio. This makes long climbs very pleasant, even for less trained drivers.
The advantage of electronic shifting systems is particularly noticeable in the front derailleur. A push of a button and the chain moves from one chain ring to the other as if by magic, without any effort. It also thinks along and automatically adjusts its position to the chain skew in order to avoid grinding noises. With the help of the Shimano E-Tube app, the front derailleur is adjusted after installation and a manual, fully or semi-synchronous shift mode is selected depending on preference.
