Built on the Blistered FF V3 shape, these wheels feature a versatile all-around profile with a sleek edge cut for a clean, responsive feel. Each wheel uses Blistered's internal bearing lock to help keep the bearing securely seated and reduce unwanted wobble. They're made from 72D real urethane, providing a firmer urethane feel while maintaining the grip and ride characteristics of urethane wheels. The 72D Ultras are especially difficult to produce and are available in very limited quantities.
