What Is the Shimano Sora RD-R3000-SS Best Used For?

The Shimano Sora RD-R3000-SS is a 9-speed road rear derailleur in short cage configuration, built for road bikes running close-ratio cassettes up to 32t. Aluminum bracket body, fluoric-coated link bushings for reduced friction and smooth cable pull, and a stainless steel B-axle deliver lightweight, durable performance for entry-level and recreational road riding. DYNAMIC INTEGRATED ROUTING cable routing keeps the cable path clean and reduces friction compared to older designs, contributing to lighter shift action over the full life of the cable.

Compatible with Shimano 9-speed Sora R3000 STI road levers. Standard 10x1 dropout hanger mount. Short cage handles a maximum 32t cog with 37t total capacity. If you are running a wider cassette up to 34t, the medium cage GS version is the correct choice. MPN: ERDR3000SS.
