This is a set of only the two parts necessary to upgrade to "Redclix RX35," a genuine option part for the Comandante grinder: * Redclix Shaft * Dedicated Red Dial The Redclix RX35 set includes these two items, as well as springs, washers, and bearings. However, these are exactly the same as those used in the standard Comandante and are not exclusive to Redclix. In other words, only these two parts are actually needed to upgrade to Redclix. I personally purchased the RX35 set for my own Comandante, but I only replaced the main two parts. The rest are kept as spares and have not been used... These two main Redclix parts were obtained from an authorized dealer of Comandante in Germany. ※ A set including the rubber band (not included in this listing) is also available. ※ Immediate purchase is welcome. ※ Please refrain from price negotiations.
