The 68mm by 43mm Seismic Tantrum is molded around the special fin-trimmed version of Seismic’s proprietary weight-saving Energy Conversion (EC) hub the first tall, wide hub seen in longboarding and still second-to-none.
The big, airy, fiber-reinforced hub combines with perfectly-refined proportions, superbly-supported radiused edges, and our advanced urethanes for a truly progressive freeride experience with quick acceleration, slide release and hookup that are always easy to read, vibrant thane lanes, and consistent wear.
