A set of Comandante genuine options: Red Clix RX35 and XL Crank Black (new and unopened). For those who haven't introduced these options yet, upgrade your Comandante C40 (MK4, MK3) all at once! <REDclix RX35> (#3809) By replacing the normal center axle shaft with the RED CLIX kit, the fineness of the grind can be increased (doubled). This is a useful option, especially when finer grind adjustments are required, such as for espresso. The pitch of the screw threads on the center axle shaft is cut twice as fine, allowing for approximately twice the precision compared to the normal version. This is a genuine part for those who want to further enhance the potential of the high-performance Comandante. <XL Crank Black> This is a genuine replacement large crank compatible with Comandante C40 Mk3/Mk4. As the name suggests, this crank consists of an XL crank, which is larger than usual, and a "Big Joe" knob (natural oak) that is slightly larger than usual. For reference, you can see a comparison photo of the two cranks I personally own. The distance from the mill's rotation axis to the knob's mounting axis is about 30mm longer, so less force is required to turn the crank. In addition, the large knob allows you to grip it firmly, so you can use your strength without waste, making grinding lighter than you might imagine. Especially when comparing with lightly roasted beans, you can really feel the difference in how easy it is to grind. Both are new and unopened.
