Ideal for the demands of competitive road racing, this Dura-Ace model ensures ultra-fast, precise and dependable gear shifting performance in all conditions.Despite its smaller, lighter design, the Dura-Ace FD-R9250 brings the fastest shifting front derailleur on the market. The fastest just got faster thanks to the Dura-Ace FD-R9250. Tipping the scales under 100 grams, the new design shifts 45% quicker than Shimano's FD-R9150, already the fastest on the market.
