The Labeda Union Wheel showcases an all-new inner core and inner ring that make it the fastest wheel Labeda has ever made. The rigid Revolver core delivers blazing speed and agility by maximizing energy transfer through each and every stride. This works with the new Apex ring that initiates wheel flex and compression earlier than past wheels, thus allowing for even quicker stops and better overall braking power. These X-Soft formula wheels are 74A hardness. Includes 1 76mm Wheel.
