Here's the newest brand of freestyle scooter wheels, the Quest Wheels!
Quest Wheels is putting the efforts where it's really needed, on the quality of the product and not on fancy looks. 

You'll get a good / solid full core slimmed down in the middle and with a smaller diameter to make more space for the USA poured urethane while maintaining a 110mm diameter.
That high profile PU means more comfort for a smoothest ride and stores more energy to keep you rolling longer and faster. As seen on the picture, the core also have dents where it connects to the PU to help against de-hubbing. 
Those wheels are only available in black (raven) and teal (Tide) for the moment. Maybe we'll see more in the futur!
