## Notes

The 24.5mm-height flat-bottom variant of IMS's B70 2-cup competition basket —
2mm shallower than the convex B702TCH26E entry, with a rounded internal
corner instead of a convex bottom. Notable because IMS's own La Marzocco
guidance recommends the H24.5 or H26.5 heights for an 18g dose on La Marzocco
machines. Same official B70 compatibility list as the other B70 entries.
Verified against the official IMS product page and catalogue on 2026-07-06.

  - Official IMS Filtri product page ('B70 2 Cups - H24.5 M Pattern'), read firsthand 2026-07-06. Specs verbatim: 'Border: Ø 70 mm', 'Body: Ø 60 mm', 'Height: 24.5 mm', tamper 'Ø 58/58.4 mm', ridge 'External Ø 60.5 mm', 641 holes in M pattern of Ø 0.30 mm over a Ø 49 mm perforated area, 'engineered with a rounded internal corner' to 'promote uniform extraction, facilitating a cleaner puck drying and easier expulsion'. Capacity 16/18g (dark roast) to 20/22.5g (light roast). IMS migrated its product URLs in 2026; this citation was repointed from the original imsfiltri.com/prodotto/ address to the canonical page that address now redirects to, re-checked 2026-07-26 (same product page, content unchanged).

  - Official IMS Competition Series catalogue, read firsthand 2026-07-04, whose 'For tamper 58 / 58.4' B70 compatibility list names La Marzocco, Rancilio, Lelit, Rocket, ECM and 'BREVILLE (The Oracle)' among the fitting brands — and 'FLAIR ESPRESSO (58)', which is why the Flair 58 is cross-referenced here; Gaggia is assigned to the narrower B68 series.
