Overview

Rear Derailleur Shimano Ultegra RD-R8150 Di2 12-speed

The Shimano ULTEGRA RD-R8150 Di2 is a next-generation 12-speed road rear derailleur that brings Shimano’s fastest and most precise shifting into a more accessible package. Featuring a single cage length option, it offers broad compatibility with 28–34T cassettes.

Delivering our fastest rear shifting ever – up to 58% faster than the RD-R9150 – the RD-R8150 combines a powerful Di2 motor with the low-profile SHIMANO SHADOW RD design for instant and seamless gear changes.

An integrated LED status indicator displays battery level, pairing status and adjustment mode information. With compatibility up to a 34T largest sprocket, it provides versatility for high-speed racing and demanding climbs alike. Firmware updates are supported via E-TUBE PROJECT.
