Rancilio Rocky Grinder Hopper - Retro-Fit Kit This complete replacement hopper kit for the Rancilio Rocky is upgraded with a retro-fit micro-adjustment adapter that adds finer grind-setting resolution than the original hopper allowed. SPECIFICATIONS Includes hopper body, hopper sticker, micro-adjustment adapter, and fixing screws for the adapter COMPATIBILITY Fits: Rancilio Rocky Replaces: Rancilio 14705011 Works with: hopper lid and bean diverter (both sold separately) INSTALLATION DIY - follow the official retro-fit instructions for the micro-adjustment adapter installation. PRO TIPS The retro-fit adapter is the real upgrade here - it gives the Rocky noticeably finer grind resolution than the stock hopper collar ever had, so it's worth doing even if your old hopper isn't damaged. The lid and bean diverter are sold separately, so budget for those if yours are also worn.
