Looking at the picture it looks like the Bezzera kit will fit the Minima, the nut and spindle look very similar to (same as?) the Lelit kit. I’m assuming that the thread size of the main nut is the same. There may be a problem with the handle fouling the casing, restricting movement of the paddle to about 190 degrees movement, but that applies to the Lelit paddle and that works.
Only one way to find out…
