The Shimano 105 Di2 RD-R7150 12-speed SHADOW RD+ rear derailleur provides fast and precise shifting and is compatible with 11-34 and 11-36 cassettes.

The next-generation SHIMANO 105 featuring Di2 draws on the design philosophy The Science of Speed bringing fresh momentum, comfort and control. It lets you embrace an open road, full of infinite possibilities. Go deeper into your journeys. See the world in a fresh new way. And enjoy the gift of each new day.

The new SHIMANO 105 brings Di2 shifting to a new set of riders. For those who have only experienced mechanical shifting and ergonomics, SHIMANO 105 Di2 represents a transformation of the road cycling experience. With function and technologies inherited from DURA-ACE and ULTEGRA, SHIMANO 105 is the culmination of years of research and development. With a shared Di2 platform, sophisticated ergonomics, SHIMANO 105-optimized gear combinations, and an exceptional brake system, the new SHIMANO 105 marks a new era of affordable performance.

The wireless Di2 offers faster and more precise gear changes on the rear derailleur. The more compact design integrates wireless unit, charging port and function button. Battery level and Bluetooth/ANT pairing status can be checked via bike computer/smartphone/tablet. In addition, the preferred shifting mode can be selected and the information on the adjustment mode can be queried (for adjusting or tuning the rear derailleur).
Triggered by the wireless shift signal of the shift lever, the extremely powerful motor of the SHIMANO 105 rear derailleur performs a shifting operation within a fraction of a second in interaction with the optimised link structure. The rear derailleur is the heart of the Di2 system and combines charging port, LED indicators, adjustment switch and more in one compact package. The flat profile reduces the risk of damage from contacts and falls.
