## Notes

The **20g-class** basket in IMS's 54mm competition line. At 26mm deep it takes
17–19.5g of a dark roast and 18–21g of a medium — noticeably more than the
14–17g the standard 24mm B62 is rated for, and the natural choice if you have
moved past Breville's stock dosing.

IMS describes the perforation on this one explicitly as **"Competition
Perforation: Relaminated and Recalibrated"** — the recalibration step is what
separates the competition line from IMS's standard baskets, tightening the
tolerance on all 583 holes so flow stays even across the puck rather than
running fast in patches.

Otherwise the familiar B62 geometry: Ø62.5mm border, Ø54mm internal body,
ridgeless, 0.30mm holes over a Ø44mm perforated area, Ø53/53.4mm tamper.

Choosing between heights is a dose question, not a quality one — see the
[22mm](/baskets/ims-b62-competition-2-cup-54mm-h22/),
[24mm](/baskets/ims-b62-competition-2-cup-54mm/) and
[28mm](/baskets/ims-b62-competition-2-cup-54mm-h28/) variants.

IMS names Breville/Sage on this product page, and each cross-referenced machine
below states a 54mm portafilter on its own manufacturer page.
