Competitors are required to ride in an upright position. Riding in the supine (lying on back) position with their feet forward or in the skeleton (on the stomach) in a head first position is prohibited.
A. DECK: The deck must be structurally sound and not pose a safety hazard. It must not possess sharp edges, which could injure riders. It may be any shape within the size limits.
B. WEIGHT: The complete board must not exceed seven kilograms (7kg / 15.4lbs). This rule will be strictly enforced. A 0.5 kg allowance will be given for variances in the accuracy of scales.
C. LENGTH: One hundred fourty centimeters (140cm / 55”) maximum.
D. WIDTH: Three hundred five millimeters (305mm / 12”) maximum.
E. TRUCKS: The trucks must be lean steer activated. They may be commercially available or custom built. They must be no more than three hundred five millimeters (305mm / 12”) wide, as measured from the outside edge of the axles. The axles cannot protrude past the edge of the wheel.
F. BEARINGS: Any bearing that fits into a hub designed to fit standard 608 Bearings. SKF 608 Bearing Specifications: Bore 8mm (0.3150”), OD Race 22mm (0.8661”), Width 7mm (0.2756”)
G. WHEELS: Wheels can be a maximum diameter of one hundred thirty millimeters (130mm / 5 1/8”). If a particular wheel proves to have a significant performance advantage and is not made commercially available* for a reasonable price, it could be specifically banned in the future.
H. NUMBER AREA: All skateboarders are required to have their IGSA assigned number located on their helmet or a bib. Helmet numbers must be placed on both sides and visible in the riding position. Bib numbers must be placed on both the front and back. Numbers must be a minimum of ten centimeters (10cm / 4”) tall. The number area and number must be of contrasting colors and be highly visible from six meters away (6m / 20’) Some promoters may issues a bib or bib panel with a number other then your IGSA assigned number. In this case the event number supercedes your IGSA assigned number. (For number assignment see section XVIII. A)
*Commercially available means the product must have been distributed to at least 24 people outside the company.
