Designed for the 12-speed era, these shifters utilize a proprietary wireless connection to communicate with the derailleurs, eliminating the need for wires through the handlebar and stem for a sleek, modern cockpit. The ergonomics have been completely overhauled with a raised hood peak and increased offset to provide more hand support and a more secure \"aero-tuck\" position. Featuring \"Servo Wave\" technology, the R8170 offers exceptional brake modulation and a lighter lever pull, ensuring total confidence on technical descents. With a battery life of up to 2 years and professional-grade shifting speed, the Ultegra R8170 is the perfect balance of elite performance and exceptional value.\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: Wireless cockpit integration simplifies bike assembly and provides a clean, cable-free aesthetic.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,1,0\"\u003eRefined Ergonomics: The taller hood shape improves hand support and allows for a more natural finger wrap, reducing fatigue on long rides.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,2,0\"\u003eServo Wave Technology: Optimizes the braking stroke for a shorter initial pad contact and deeper, more intuitive modulation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,3,0\"\u003e12-Speed Hyperglide+: Engineered to provide smooth, instantaneous shifts even under high pedaling loads while climbing or sprinting.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,4,0\"\u003eIntegrated Buttons: Hidden buttons on the top of the hoods allow for controlling ANT+ compatible GPS head units (Garmin\/Wahoo) or auxiliary shifting.\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: Ultegra R8100\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 Ultegra ST-R8170-R (Right\/Rear Shifter)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,1,0\"\u003eShimano Ultegra ST-R8170-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":54279331905908,"sku":null,"price":64900.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/1991\/6660\/files\/shimano-ultegra-di2-st-r8170-2x12-fach-sti-einheit-set-istr8170lf-istr8170rf_a.jpg?v=1775474932","url":"https:\/\/velorays.com\/products\/shimano-ultegra-di2-st-r8170-2-12-speed-shifters","provider":"Velorays","version":"1.0","type":"link"}
