Sold as a set of 4 wheels
Ricta Clouds have a wide variety of sizes and hardness to cover the range of surfaces and styles of skateboarding that exist. You wouldn't ask a fish to climb a tree, why ask your wheels to do what they don't do best either?
The 60mm, 78a Ricta Clouds are the biggest softest wheel in the line up. Great for those rough concrete bigger crack and rough stuff wheel needs.
