Grind wheels - Aggressive skating

Grind wheels, as the name implies, are made for grinding in aggressive skating and not for rolling on. This is also why the wheels are significantly harder than normal aggressive wheels. They stabilize your grind to make it easier for you to keep balance and, apart from this, they protect your frame from wear and tear. The diameter of grindwheels is smaller than normal wheels and they are placed as the two center wheels on the frame (on an anti-rocker setup).
