The Native Profile Wheels is the all new offering, and features an all new urethane-to-core ratio. The new ratio has been optimized to have better compression and durability. The urethane is on the softer side so they feel smooth, fast, and will grip on all surfaces. This is the 115mm x 30mm wide version of the wheels. This is NOT the industry standard so please make sure your fork/deck is compatible with them before purchasing.
