Pyoranosat ROSE | Shimano Dura Ace Fd-R9150 F Front Derailleur

The Shimano Dura Ace Fd-R9150 Front Derailleur Stands Out For Full Di2 System Integration And Ensures Perfect Shifting Processes For Training And Competition. In The Latter Case, The Synchro Shift Feature Helps You To Completely Focus On The Race, As It Automatically Adjusts The Rear Derailleur In Combination With The Front Derailleur For A Perfect Chainline And Gear Use. In The Full Synchro-Shift Mode, The Front Shifting Is Automatically Controlled Based On Your Rear Gear Use. The Semi Synchro-Shift Mode Can Be Set Up To Adjust Your Rear Gear Position Based On Your Manual Front Chainring Choice. So, Shifting At The Front Will Enact Automatic Shifts At The Back To Keep A Consistent Cadence.
