Omni-Directional wheels roll forward like normal wheels, but slide sideways with almost no friction (no skidding during turns). These wheels are the same size as the VEX 3.25" Traction Wheels. Removable wheel inserts allow for additional versatility - use these wheels with either standard Drive Shafts or High Strength Shafts, in either a driven or free spinning application.
