{"product_id":"shimano-ultegra-rd-r8150","title":"Shimano Ultegra RD-R8150","description":"\u003cp data-path-to-node=\"1\"\u003eThe Shimano Ultegra RD-R8150 is the central nervous system of the R8100 12-speed Di2 series, delivering the fastest and most precise shifting ever seen in the Ultegra lineup. Following the architecture of the flagship Dura-Ace model, this derailleur now integrates the system's wireless transceiver, charging port, and LED status indicator into a single, sleek unit. With shifting speeds increased by 58% over the previous generation R8050, the RD-R8150 provides near-instantaneous gear changes. Its single-cage design is highly versatile, capable of handling everything from an 11-28T to an 11-34T cassette, making it the perfect choice for both competitive road racing and challenging alpine climbs.\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\"\u003eIntegrated Wireless Functionality: Houses the \"brain\" of the Di2 system, enabling wireless communication with shifters and Bluetooth\/ANT+ connectivity for the E-TUBE PROJECT app.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,1,0\"\u003eUnified Charging Hub: Features an integrated magnetic charging port (EW-EC300), eliminating the need for a separate junction box and simplifying the cockpit.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,2,0\"\u003eShadow RD Design: The low-profile silhouette stays tucked under the cassette, reducing aerodynamic drag and protecting the derailleur from impact damage.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,3,0\"\u003eLightning-Fast Response: Engineered for 58% faster rear shifting compared to the 11-speed R8050, ensuring you never miss a gear during a sprint.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,4,0\"\u003eSingle Cage Versatility: A medium-length cage (GS-style) is standard, providing compatibility with high-range 34T cassettes without needing a specialized long-cage version.\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: 12-Speed Di2\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,1,0\"\u003eMaximum Low Sprocket: 34T\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,2,0\"\u003eMinimum Low Sprocket: 28T\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,3,0\"\u003eTotal Capacity: 37T\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,4,0\"\u003ePulley Teeth: 11T\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\"\u003eRD-R8150 Rear Derailleur\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,1,0\"\u003eB-Axle Washer\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,2,0\"\u003eUser Manual\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,3,0\"\u003e\u003ci data-path-to-node=\"7,3,0\" data-index-in-node=\"0\"\u003e(Note: EW-EC300 Charging cable sold separately)\u003c\/i\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shimano","offers":[{"title":"Black \/ Rear Derailleur Only \/ Wireless Setup (Standard)","offer_id":54343651459444,"sku":null,"price":46020.0,"currency_code":"INR","in_stock":true},{"title":"Black \/ Rear Derailleur Only \/ Wired Setup (Requires SD300 Cables)","offer_id":54343651492212,"sku":null,"price":46020.0,"currency_code":"INR","in_stock":true},{"title":"Black \/ Rear Derailleur + EW-EC300 Charging Cable \/ Wireless Setup (Standard)","offer_id":54343651524980,"sku":null,"price":46020.0,"currency_code":"INR","in_stock":true},{"title":"Black \/ Rear Derailleur + EW-EC300 Charging Cable \/ Wired Setup (Requires SD300 Cables)","offer_id":54343651557748,"sku":null,"price":46020.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/1991\/6660\/files\/636e0d95c798cd546855c72d-shimano-ultegra-rd-r8150-di2-rear.jpg?v=1775845493","url":"https:\/\/velorays.com\/es\/products\/shimano-ultegra-rd-r8150","provider":"Velorays","version":"1.0","type":"link"}
