Carver boards demand the highest grip levels from any wheel. That is why carver have come up with the Roundhouse concave wheel. It comes in to its own when powering through a carve or smashing a cut back! Roundhouse Concave Wheels give you extra projection out of your turns so you can complete manoeuvres you’d otherwise slide out on. The key to this design is the concave riding surface which, when under weight, produces an hourglass-shaped contact patch. This increases the surface area and pushes the lip into the ground, creating more grip than ever before while maintaining consistent roll speed. These are the grippiest wheels you’ll ever ride! Specs: 69mm x 52mm, and are a soft 78a.
