For the new DURA-ACE 9100 series, Shimano has redeveloped every single system component in order to create the most innovative component group of all time.
The derailleur cable routing has been adapted to further reduce the force applied when shifting gears. The precise and easy adjustment of the front derailleur offers more cable routing options and an integrated adjustment of the tension. With its optimized gear ratio in combination with the ST-R9100 switching | Brake lever and the coated cables, the new Dura Ace front derailleur ensures both shorter lever travel and lower shifting forces.
