This latest 12-speed generation introduces a semi-wireless connection, where the shifters communicate wirelessly with the derailleurs to provide a clutter-free, elite-level cockpit. The ergonomics have been radically refined with a raised hood peak and an inward-curving body to provide a more secure grip and better aerodynamic tuck. Featuring \"Servo Wave\" technology inherited from Shimano’s MTB brakes, these shifters offer unparalleled modulation and a lighter lever action than ever before. With a battery life of up to 2 years and a 58% faster rear shifting speed than the previous generation, the R9270 is the ultimate choice for professional-level racing and flagship bicycle builds.\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\"\u003eSemi-Wireless Di2: Eliminates the need for wires running through the handlebar to the frame, ensuring a clean aesthetic and simplified assembly.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,1,0\"\u003eEnhanced Ergonomics: Raised hood peaks improve leverage and hand support when riding in the \"aero-hoods\" position.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,2,0\"\u003eServo Wave Technology: Optimizes brake control with a shorter initial stroke and improved power modulation for technical descents.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,3,0\"\u003e12-Speed Hyperglide+: Works in harmony with the R9200 drivetrain to allow for seamless shifting even under maximum sprinting loads.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,4,0\"\u003eIntegrated Switches: Hidden \"Third Buttons\" on the hood tops for controlling ANT+ GPS head units or auxiliary shifting functions.\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\"\u003eSeries: Dura-Ace R9200\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,1,0\"\u003eConnectivity: Di2 Wireless (Proprietary), Bluetooth\/ANT+ (via EW-EC300)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,2,0\"\u003eShifter Type: Dual Control Lever (2×12-Speed)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,3,0\"\u003eBrake Compatibility: Hydraulic Disc (Mineral Oil)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,4,0\"\u003eLever Material: Carbon Fiber Reinforced Plastic (CFRP)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,5,0\"\u003eBattery: CR1632 (Approx. 1.5–2 year life)\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\"\u003eShimano Dura-Ace ST-R9270-R (Right\/Rear Shifter)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,1,0\"\u003eShimano Dura-Ace ST-R9270-L (Left\/Front Shifter)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,2,0\"\u003eTwo CR1632 Batteries (Pre-installed)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,3,0\"\u003eBrake Hose Fixing Bolts and Plugs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,4,0\"\u003eUser Manual and Setup Guide\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shimano","offers":[{"title":"Black","offer_id":54279311786356,"sku":null,"price":92040.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/1991\/6660\/files\/6355c0b5_str9270r.webp?v=1775472376","url":"https:\/\/velorays.com\/products\/shimano-dura-ace-di2-st-r9270-2-12-speed-shifters","provider":"Velorays","version":"1.0","type":"link"}
