Cortech Disk Model

These Cortech Disk wheels are fast. I don't know why, but they just are. Apparently, there is a 75A disc buried inside the white wheel, which is what makes it faster. How does this work though? Who knows? Who cares? All I know is that the designer is brilliant at chemistry, and made the two pieces bond perfectly, and it's a one piece wheel. And the resiliance (look that word up in the dictionary) is better, as the 75A core is present. The wheels do not sit in the core, unlike their other model (which is for vert) ride these on the street, and you know that everyone will be going; "look at him, I bet he's riding CORTECH WHEELS"
