The Tracker was also introduced at the derby nationals with great response. This wheel is best used as a traction/pusher "7 spoke" combination allows for maximum grip on all surfaces. Trackers work really well on uncoated floors and concrete, and have the perfect amount of grip when you really need to wind up and blast someone to keep them from scoring.
