The first turn with the longer crank feels different: the grounds give way more easily, your hand gets more leverage, and the ergonomic wooden knob sits snug between your fingers. The Black Crank turns your morning grind into a calmer, more pleasant ritual.
It’s the official XL crank upgrade for every Comandante C40 Mk3 and Mk4. The extended shape delivers noticeably more leverage — especially with light roasts and fine grind settings. The included “Big Joe” knob, made from solid, black lacquered oak (Ø 55 mm), makes grinding more comfortable.

For anyone who grinds larger quantities more often, enjoys working with light roasts that offer more resistance, or simply wants more ergonomics and style on their grinder. Nobody needs the XL crank — you either want it, or you don't. Matching spare parts are available in the Comandante Spare Parts Selection, and more grinders in the Coffee Grinders.
