Shimano Dura Ace 9000 11 Speed Mechanical Front Derailleur
The FD-9000 claims a 43% reduction in shifting effort compared to 7900. That’s an enormous improvement. This is helped along by Shimano’s polymer-coated shift cable, which nearly eliminates mechanical drag. Shimano then shortened the lever stroke by manipulating the leverage at the front derailleur. All this adds up to shifting that’s on par with Shimano’s Di2 system.
