Shark Wheel California Roll Purple 60mm/78A

60mm - 78a - Skateboard Wheels 
Fast, soft and superior grip
Best wheel in the world over rough terrain (pebbles, debris, sand, water, etc)
Made in California

1.  Rough Terrain. The best wheel over rough terrain. The sine wave shape tends to kick pebbles and small objects out of the way. Also, the best wheel over wet conditions. Scientifically proven by San Diego State University, Mechanical Engineering Department. 

2.  Approach Angle. Shark Wheels perform similar to how drivers intuitively know to go over a speed bump at an angle to reduce the shock in their car. The unique 30-degree approach angle of the Shark Wheel reduces shock and deflects objects due to its approach angle. A normal wheel is a steamroller and tries to go over obstacles in its way. Shark Wheels tend to move around objects.

3. Lasts Longer. Scientifically tested to last up to 50% longer when cruising. Shark Wheel has multiple center points compared to one center point on a traditional wheel. Scientifically proven by San Diego State University, Mechanical Engineering Department. Flatspot resistant.

4. Better Slide Control. The Shark Wheel actually spins as it slides acting like a car's antilock brakes. The 3 lips of the Shark Wheel compared to 1 lip on a traditional wheel give predictable slides. Also, slides are easier to perform due to less surface area in contact with the ground. Less friction to initiate a slide.

5. Lightning Fast. 57% less rolling resistance than a traditional wheel. Scientifically proven by the largest caster company in the world.
