The 54mm portafilter standard
54mm is Breville's proprietary home-machine size (sold as Sage in the UK/Europe). Standard 58mm baskets and accessories do not fit these machines — you need parts made specifically for the 54mm format. Breville ships both single-wall (non-pressurized) and dual-wall (pressurized) baskets with most of these machines.
