The Type-S goal has been to design a version of a skateboard wheel that had more than looks, graphics, and function, and applying what they tested into their own creation of what they feel really works in a skateboard wheel. Type-S has taken decades of their own skating experiences with the combination of years of research and development to design these functional, yet proper skateboard wheels with added details only people who really skate understand and notice. The Modified 96a Wheels are your all-terrain wheels. Made with quality urethane. Available in sizes as seen below. Graphics on both sides.
