Shark wheels are amazing, I have them on all of my skateboards now. Until you actually try them yourself you won’t understand how awesome they are. They just glide over rough terrain compared to normal wheels which you feel the vibrations. So far everyone of my friends that has tried mine has gone and bought their own pair. I normally don’t write reviews, but this is really a great product and a great crew of people working there if you get the chance to stop into their facility.
This is my third set of Shark Wheels (I'm replacing all my wheels on all my boards with SWs) and once again, they're amazing. Ride great. Handle dirt and rocks great. Look great.
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.
