These are burr set upgrades for anyone that already preordered a grinder for the end of May shipment. We have a limited number of SSP burrs that we were able to order and will install them prior to shipment if you order them ahead of time. Please put your Turin 64SD order number in the order comments when placing the preorder for the burr upgrade. We are offering High Uniformity burrs designed for espresso only and unimodal burrs designed as all purpose burrs.
You will also get the Turin 64SD original burrs if you ordered a Turin grinder from us and want these installed with your order.
