Why choose the Comandante Black Crank – XL Crank with Big Joe Knob
Longer Lever = Less Effort
The XL axle extends the rotation arc — you apply more torque per turn to the burr set without more muscle effort. With light, dense specialty beans and larger doses (18 g+), it's noticeably more relaxed.

Pro Tips:
Don't crank too fast — the XL geometry yields its benefits at normal rotation speed (~1 rotation per second). Too fast creates more burr heat.
Clean the wooden knob only dry — water or detergent can bleach the black lacquer over years. A dry microfiber cloth is enough.
If the crank is hard to attach the first time: the lever sits on a tapered fit that develops slight play over time. On first attachment, just press a bit firmer.

FAQ
Product information
General information
Shipping & Delivery
Does the Black Crank fit my C40 MK4?
Yes — 100% compatible with all C40 MK3 and MK4 (Standard, LAB Series, all color variants). Not for C40 MK2 or older (different axle system), also not for C60 Baracuda.
How do I swap the crank?
Unscrew the standard crank clockwise (lift it against the body), attach the Black Crank, twist counter-clockwise to tighten. No tools needed. Time: under 30 seconds.
Is the XL lever really noticeably better?
At normal doses (10–14 g), you notice the difference less. With larger doses (18 g+) and dense beans (light naturals, anaerobic), the XL variant is significantly more relaxed — about 20–30% less hand force per click.
Does the black coating hold up?
Yes — Comandante uses an abrasion-resistant powder coat that stays black even under heavy use. After years, the wooden knob may develop a slight patina, the axle stays black.
