The Roundhouse Concave is the grip wheel in the Carver lineup. The concave riding surface creates an hourglass-shaped contact patch under load — as you lean into turns, the lip compresses and pushes into the ground, increasing surface area and grip when you need it most. The 78a durometer keeps things smooth and fast on rough pavement while maintaining strong traction through carves.
At 69mm with a 52mm contact width, these wheels are tuned for riders who push hard into turns and want full confidence that the wheels will hold. Smoke colorway.
