DURA-ACE Di2 FRONT DERAILLEUR 2X12s
DURA-ACE Di2 前變速器 2×12 速
Our 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 our fastest. The frontal area of the FD-R9250 is also reduced decreasing aerodynamic drag.
DURA-ACE FD-R9250 能讓我們以最快的速度再創佳績。 全新設計重量不到 100 公克，具備扭轉形勢的能力，其變速速度比 SHIMANO FD-R9150 快 45%，是我們有史以來最快的速度。 FD-R9250 的正面體積也有所縮小，能夠減少空氣動力風阻。
