The bottomless (naked) counterpart to Lelit’s spouted LELIT58 filterholder. Removing the spout exposes the underside of the basket so you can watch the extraction directly — even, mirror-like flow means an evenly tamped, evenly distributed puck, while sprays and jets pinpoint channeling. It is the single most useful diagnostic tool for dialling in a grinder, which is why “Lelit bottomless portafilter” is such a common search among Bianca and Elizabeth owners.
Lelit’s page states it is “For machines with LELIT58 group” and ships with a “stainless steel 2 doses PLUS filter (18-21 g), in collaboration with IMS” — so it arrives ready to pull an 18–21 g double. The LELIT58 group is Lelit’s 58mm commercial standard, used on the Bianca, MaraX, Elizabeth, Victoria and Kate, all cross-referenced here. It does not fit the 57mm Anna (Lelit’s narrower LELIT57 group), and as a standard 58mm portafilter it accepts any 58mm basket — the VST and IMS B70 precision baskets in this database drop straight in.
