The Rollerblade 3WD 110 Urban Frames Complete with Wheels have wheels already installed and ready to roll. They mount on with 165mm mounting and the frames measure 255mm (10") in length. At such a short length they are agile and perfect for urban skating. The frames are made of extruded aluminum, making them very responsive but also strong so that they can endure rougher conditions. 

The Hydrogen Rollerblade wheels come as a 3x110mm set up and they have an 85A hardness. The urethane is poured in the US and is high performing, they have a great amount of grip and durability. In those wheels, Twincam ILQ-9 Classic bearings are installed with spacers that ensure their roll.
