Smoothest wheel in town
Love the smoothness of these wheels, so much so; that all my boards have shark wheel installed on them. Once broken in they also good for your occasional slide here and there. Plus the bearing are definitely awesome too. I mainly do freestyle and dance. At first I used only the 70mm, but the 60mm wheels are now my favorite. I have Loaded, Apex, Timber & Ehlers longboards and the wheels are equally awesome on each board.
Shark Wheels are amazing
The width is increased, but the friction is decreased! The sine wave design provides three lips per wheel for superior lateral grip. When you want to slide, they break away smoothly and recover easily.
The wave pattern design allows for a thin contact patch touching the ground and therefore less friction, resulting in a quicker ride.
The alternating pattern of grooves significantly reduces hydroplaning by channeling liquid, sand or gravel out and away from the surface of the wheel, allowing for a firm contact patch with the ground.
