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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eShimanos fastest front shifting, 45% faster than FD-R9150\u003c\/li\u003e\n\u003cli\u003eFrontal area reduced by 33%\u003c\/li\u003e\n\u003cli\u003eWeight cut to 96g\u003c\/li\u003e\n\u003cli\u003eTop gear teeth capacity: 50-55T\u003c\/li\u003e\n\u003cli\u003eThe biggest difference you will notice is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under load\u003c\/li\u003e\n\u003cli\u003eThe 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\u003c\/li\u003e\n\u003cli\u003eThe 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\u003c\/li\u003e\n\u003cli\u003eBraze-on fit as standard; if your bike does not have a braze-on mount seat Tube adapters are available\u003c\/li\u003e\n\u003cli\u003e12-speed E-tube SD300 wire compatible\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shimano Dura-Ace","offers":[{"title":"Black \/ 12-Speed","offer_id":42266009239731,"sku":"FDR9250F","price":221.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0568\/3065\/6691\/products\/fd-r9250-di2-12-speed-double-front-derailleur-black-12-speed-1179340436.jpg?v=1793176701","url":"https:\/\/www.biketart.com\/products\/shimano-dura-ace-fd-r9250-di2-12-speed-double-front-derailleur","provider":"Biketart","version":"1.0","type":"link"}
