There is a version of Ode Brew Grinder from early development that is, unfortunately, not guaranteed to be compatible with 64mm SSP burrs. To check if you have one of these units, look for the 19-digit serial number beneath your Ode.
If the combination of numbers in digits 12-14 is 210 and higher (e.g., 210, 211, 212, 301, 302, etc.), then your Ode Brew Grinder will accept SSP burrs! All 64mm SSP burrs are compatible with your Ode Brew Grinder.
If the combination of numbers in digits 12-14 is below 210 (e.g., 209, 208, 110, etc.), then, unfortunately, your Ode Brew Grinder will not accept SSP burrs.
All Ode Brew Grinders will accept Fellow Ode Gen 2 Brew Burrs, regardless of when the grinder was manufactured.
