The original BOOST Kit (V1) was only supplied with a small ring. The large ring ensures that larger amounts of beans are better held in the roasting chamber.
⚠️ Note: In the current version of the BOOST Kit (V2), the large ring is already included.
👉 Important: This product is not the complete BOOST Kit, but only the large ring – ideal for anyone who owns the older BOOST Kit (V1) and wants to expand it.
