We are always looking for ways to reduce our carbon footprint and create a more eco-friendly rider experience. The Roundhouse Ecothane Concaves are made in the USA from a unique formula that incorporates soybeans to offset the reliance on petroleum-based urethane.

The need for grip has never been more important than in surfskate, where you rely on the traction of the wheels to fully lean into carves and cutbacks. Roundhouse Concave Wheels give you extra projection out of your turns so you can complete maneuvers youd 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 youll ever ride!
