SHIMANO DURA-ACE DI2 R9250 2x12-Speed Front Derailleur Braze-On

Always remarkable for its compact and lightweight appearance, the SHIMANO Dura-Ace Di2 9250 front derailleur features a weight further reduced by 8 grams compared to 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, the synchronised shifting allows the cyclist to manage only their right-hand lever ("Full Synchro Shift"), a simple sprocket change on the cassette automatically influencing the chainring selection at the front, to preserve the chainline and cadence. A "Semi Synchro Shift" mode is also available: only the chainring lever is then managed, and the chain automatically aligns to the correct gear on the cassette!
