Despite its smaller and lighter design, the Dura-Ace R9250 offers Shimano's fastest front shifting yet. This new, sleeker front derailleur is not only under 100 grams but also shifts 45% quicker than its predecessor, the Dura-Ace R9150. Additionally, the reduced frontal area of the FD-R9250 decreases aerodynamic drag, making it an exceptional upgrade for performance-focused cyclists.

Features:

• Shimanos fastest front shifting, 45% faster than FD-R9150
• Frontal area reduced by 33%
• Weight cut to 96g
• Top gear teeth capacity: 50-55T
• The biggest difference you will notice is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under load
• The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts
• The front derailleur also trims automatically; the cage moves in response to the position of the rear derailleur on the cassette to ensure no chain rub and a quiet unobtrusive ride, enabling you to concentrate on the road ahead
• Braze-on fit as standard; if your bike does not have a braze-on mount seat Tube adapters are available
• 12-speed E-tube SD300 wire compatible
