SHIMANO DURA-ACE DI2 R9250 2x12V Braze-on Front Derailleur

As remarkable as ever for its compact, airy appearance, the SHIMANO Dura-Ace Di2 9250 front derailleur front derailleur weighs 8 grams less than the previous-generation 9070 model.

This derailleur now allows 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, Synchronized Shift offers the rider the possibility of managing only the right-hand control ("Full Synchro Shift"), with a simple sprocket change on the rear derailleur. Cassette automatically influences the selection of the Chainring to the front, preserving chain line and cadence. Semi Synchro Shift" mode is also available, with only the front and rear sprockets controlled. Chainrings control is then managed, and the chain automatically aligns itself, at the right development, on the Cassette !
