{"product_id":"shimano-dura-ace-fd-r9250","title":"Shimano Dura-Ace FD-R9250","description":"\u003cp data-path-to-node=\"1\"\u003eThe Shimano Dura-Ace FD-R9250 is the fastest and most sophisticated front derailleur Shimano has ever engineered. As a core component of the 12-speed Di2 ecosystem, it features a frontal area reduced by 33%, significantly decreasing aerodynamic drag and weight. Shifting speed has been increased by 45% compared to the previous generation, resulting in near-instantaneous chain movement even under high pedaling loads. With its integrated electronic intelligence, the FD-R9250 eliminates the need for manual trimming, automatically adjusting its position to prevent chain rub as you move through the rear cassette.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eKey Features\u003c\/p\u003e\n\u003cul data-path-to-node=\"3\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,0,0\"\u003eUltra-Fast Shifting: A redesigned high-torque motor delivers the fastest front shifts in Shimano's history (45% faster than R9150).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,1,0\"\u003eCompact Aerodynamic Profile: 33% smaller frontal area reduces wind resistance and provides better clearance for wider tires.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,2,0\"\u003eAuto-Trim Technology: The derailleur communicates with the rear system to automatically adjust its cage position, ensuring a silent drivetrain in every gear combination.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,3,0\"\u003eHigh-Rigidity Cage: Optimized for the high-torque shifting required by professional sprinters and climbers.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,4,0\"\u003ePlug-and-Play Integration: Connects via the SD300 wiring system for simplified setup and maximum weather resistance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"4\"\u003eSpecifications\u003c\/p\u003e\n\u003cul data-path-to-node=\"5\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,0,0\"\u003eDrivetrain Speeds: 2x12 Speed Di2\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,1,0\"\u003eTop Gear Teeth: 50T - 55T\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,2,0\"\u003eChainstay Angle: 61° - 66°\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,3,0\"\u003eChainline: 44.5mm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,4,0\"\u003eMounting: Braze-on\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,5,0\"\u003eWiring System: EW-SD300\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"6\"\u003eTypical Components Included\u003c\/p\u003e\n\u003cul data-path-to-node=\"7\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,0,0\"\u003eFD-R9250 Front Derailleur\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,1,0\"\u003eBackup Bolt (for frame support)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,2,0\"\u003eSetup Tool\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,3,0\"\u003eUser Manual\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shimano","offers":[{"title":"Front Derailleur Only \/ Standard (Braze-on) \/ Black","offer_id":54343624851828,"sku":null,"price":50150.0,"currency_code":"INR","in_stock":true},{"title":"Front Derailleur Only \/ Braze-on with Clamp Adapter (31.8mm\/34.9mm) \/ Black","offer_id":54343624884596,"sku":null,"price":50150.0,"currency_code":"INR","in_stock":true},{"title":"Front Derailleur + SD300 Wire Bundle \/ Standard (Braze-on) \/ Black","offer_id":54343624917364,"sku":null,"price":50150.0,"currency_code":"INR","in_stock":true},{"title":"Front Derailleur + SD300 Wire Bundle \/ Braze-on with Clamp Adapter (31.8mm\/34.9mm) \/ Black","offer_id":54343624950132,"sku":null,"price":50150.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/1991\/6660\/files\/108817.webp?v=1775844500","url":"https:\/\/velorays.com\/es\/products\/shimano-dura-ace-fd-r9250","provider":"Velorays","version":"1.0","type":"link"}
