Our beloved Cry Baby wheels grew up, went to college, and became the Tantrums: the lightest and most functional freeride wheels of their size on the market!

The 68mm by 43mm Seismic Tantrum is molded around the special “fin-trimmed” version of our 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:
• quick acceleration
• slide release and hookup that are always easy to read
• vibrant ‘thane lanes
• consistent wear
