With the old-style plain wheels, you could grease the bearings simply by removing the rubber cap at the end of the hub, which exposed both the zerk and the rim-gap where old grease emerges. But my 2020 2720 has sexy aluminum wheels! Those wheels have a removable cap in the center, and removing the caps lets you remove the rubber cap under it. But the rim-gap is covered. Bottom line - in order to grease the bearings using the EZ-Lube hubs, I have to remove the wheels.
