SHIMANO DURA-ACE Di2 R9150 2x11-Speed Front Derailleur Braze-On

Still as remarkable for its compact and airy appearance, the SHIMANO Dura-Ace Di2 9150 front derailleur is now 10 grams lighter than the previous generation model 9070.

This derailleur now enables the use of the "Synchronized Shift" function, introduced by the Japanese manufacturer in its latest Dura-Ace electronic transmission systems! With the aim of simplifying gear management, synchronised shifting gives the cyclist the option of only managing their right-hand control ("Full Synchro Shift"), where a simple sprocket change on the cassette automatically influences the chainring selection at the front, to preserve the chain line and cadence. A "Semi Synchro Shift" mode is also available: only the chainring control is then managed, and the chain automatically aligns to the correct development on the cassette!
