This complete skateboard features an authentic Flexdex Fiberglass Deck paired with premium mechanical hardware from the turn of the millennium. This entire platform was meticulously engineered in the late 1990s/early 2000s specifically for quick-carving slalom lines and high-energy “pumping” (generating forward speed purely through turning). Premium Hardware Breakdown. Vintage Flexdex Fiberglass Deck: Features the classic, bright yellow/orange racetrack graphic with the original stylized Flexdex “F” logo. Built from their signature high-tensile fiberglass composite, this deck delivers a uniquely snappy, virtually indestructible flex profile that perfectly mimics surf-style carving on asphalt. 1st Gen Vintage Seismic Spring Trucks: Highly collectible mechanical trucks that swap out typical rubber bushings for twin high-rebound steel coil springs. Fully stamped with the iconic concentric radar logo and original U. Patent #5,263,725. Outfitted with red springs for a perfect balance of deep carving response and high-speed stability. Kryptonics Classic K 65mm Wheels: Authentic, vintage amber gummy wheels. These 65mm wheels feature a soft, grippy durometer profile that locks onto the concrete, allowing aggressive leaning angles during hard turns without sliding or washing out. Condition Notes: This is a pre-owned, vintage complete setup with beautiful character. The deck and graphic show typical cosmetic signs of surface riding wear, minor scuffs, and superficial scratches consistent with age. The fiberglass deck structurally retains its incredible, snappy flex integrity with zero structural delamination. Trucks, bearings, and steel springs remain mechanically sound, compressing and articulating beautifully.
