Complete your Set-Up with the Ceado Quick Set Gear Ceado grinders have always been prized for their precision and consistency, delivering innovation after innovation to better refine espresso preparation in the home. The Ceado Quick Set Gear marks another step forward, allowing you to upgrade from the previous lever adjustment mechanism of your E37S to an intuitive worm gear. The Quick Set Gear is decidedly easier to use and affords much greater accuracy when adjusting your grind. All it takes is a simple twist. The worm gear itself is made of brass and easily the most heavy-duty worm gear we've seen on the market. It won our confidence the moment we got our hands on it. You can expect the Quick Set Gear to make your E37S a much more accessible and efficient piece of equipment, and we're certainly happy to see one of our favorite grinders get even better. Note: The Quick Set Gear Upgrade Kit is compatible with Ceado E37S grinders with serial numbers beginning with F, G, or H.
