Faster than ever before, the 12-speed road groupset scores with unparalleled control and comfort anytime and anywhere – whether in an everyman race, on the hunt for a personal best time, or on a companionable ride.\u003c\/p\u003e\n\u003cp\u003eAs with the Dura Ace R9200, not only does Hyperglide+ make its way into the Ultegra's components, but also its Di2 parts rely on Wireless technology to simplify operation and ensure smooth shifting.\u003c\/p\u003e\n\u003ch4\u003eHIGHLIGHTS\u003c\/h4\u003e\n\u003cp\u003eThe Di2 actuators in the front and rear derailleurs of the current Ultegra series enable a significantly higher movement speed for a shorter movement time when changing gears and correspondingly rapid shifting processes.\u003c\/p\u003e\n\u003cp\u003eThe Shimano Ultegra Di2 RD-R8150 rear derailleur speeds up the shifting process by 58 % compared to the previous generation Dura Ace model RD-R9150. The rear derailleur with a uniform cage length and an increased gear ratio of 34 teeth is thus not only faster than ever before, but also guarantees highly precise functionality under all conditions.\u003c\/p\u003e\n\u003cp\u003eThe built-in transmitter ensures wireless communication with the STI brake\/shift levers, ensuring podium-worthy, lightning-fast, and precise shifting. Using Bluetooth and ANT+, it is also responsible for data transmission to the E-Tube Project and E-Tube Ride apps as well as to third-party devices.\u003c\/p\u003e\n\u003cp\u003eBesides the charging port, the Top Normal rear derailleur features a button for certain Di2 settings and an LED for status display informing you about battery level, pairing, and setting mode, for example.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePorts: \u003c\/strong\u003e1x EW-SD300, 1x EW-EC300\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShadow RD -\u003c\/strong\u003e With their sophisticated technology, Shimano Shadow RD rear derailleurs are especially intended for a more aggressive riding style. Their super low-profile design carries many benefits. Thanks to the low profile and a single tension construction, the derailleur does not hit the chainstay in rough riding conditions. The result is a smooth and silent performance.\u003c\/p\u003e\n\u003ch4\u003eSPECIFICATIONS\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsage Bikesport\u003c\/strong\u003e: Road Bike\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShifting System (Manufacturer)\u003c\/strong\u003e: Shimano\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber Of Gears - Rear\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShifting Type\u003c\/strong\u003e: Chain - Electronic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmallest Sprocket\u003c\/strong\u003e: 11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Derailleur Cage\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Derailleur Max.
