• a central opening configured to align with a central opening within the wheel, wherein the outer face expands radially outwards with respect to the central opening;
• a first inner face continuously connected to the outer face via a first horizontal wall,
• and
• a second inner face continuously connected to the first inner face via a second horizontal wall, wherein the second horizontal wall is configured to friction fit against an internal wall within the well of the skateboard wheel,
• wherein the grinding device is configured to provide a contact buffer between a surface on an inner side of the wheel and object on which the skateboard is grinded when installed into the skateboard wheel.
