The Shimano Dura Ace Di2 FD-R9250 front derailleur makes fast shifting systems even faster. Thanks to its revised design, its weight is not only less than 100 grams, the Down Swing front derailleur also performs shifting operations 4 5% faster than the predecessor model FD-R9150. In order to also cut a good figure in terms of aerodynamics, the frontal area has also been reduced by 33 %.
