Ricta Wheel Dynamics 52mm Speedrings Slim 99a.

Ricta Speedrings' give you the feel of a traditional wheel with the speed and reduced rolling resistance of a cored wheel. The unique core design puts urethane around the bearing bore like a non-cored wheel and the inner core design helps maintain shape integrity when landing tricks for quick rollaway.

Ricta's lightweight Slim shape features a thinner profile for minimal drag and a medium width riding surface for smooth, predictable slides.
