Training Wheel (International Version)

Designed for for both Instructors and Students, the Training Wheel is a wonderful tool to clearly show the relationship between the Six Directions and the Three Dimensions.
Easily explain and demonstrate:

• Six Directions
• Three Planes
• Three Dimensions
• Movement & Rotation
• Pivoting & Rolling
   
• Point
• Line
• Cross
• Circle
• Directions of Force

Extremely versatile, each component can function as a stand-alone tool, and can also be combined in various combinations to highlight different relationships.
