Product Description
The Shimano Ultegra RD-R8150E Di2 rear derailleur brings fast, precise 12-speed electronic shifting to modern Shimano road builds. Designed around Shimano’s latest Di2 platform, it combines quick shift response with a compact integrated design that includes the wireless unit, charger connection, and status functions in one clean package.
This medium cage version is Shimano’s versatile Ultegra 12-speed option, compatible with 11-28T, 11-30T, and 11-34T cassettes. It supports a 34T maximum low sprocket and offers a 39T total chain wrap capacity, making it a strong choice for a wide range of 2x12 road setups.
This derailleur is in take-off condition and may show light handling marks, small scuffs, or minor signs of installation/removal. Any wear present is expected to be cosmetic only unless otherwise noted.
