SSP Burrs are now available in the UK but are not compatible with all Fellow Odes. Only Fellow Ode grinders from Q3 2021 onward are built to fit the SSP multipurpose burrs, the means models marked as Q4 2021, Q1 2022 & Q2 2022, and so on will be compatible.
Ode grinders before this date can still fit the SSP burrs but it is a tighter fit for the chamber as they are not designed to fit.
