Seismic Tantrum


Seismic Tantrum


The Tantrum is Seismic’s freeride wheel. Poured using their buttery Elixir formula, these wheels are big enough to get a decent bit of speed but designed to break into a controllable, predictable slide when you want it – and only when you want it.

Looking to get sideways? This is the wheel you want.

Seismic Tekton 7 Ball Bearings

These aren't just cheap, off-the-shelf bearings with a custom shield. Tektons feature a built-in spacer with a unique flange, locking the bearings together on the axle and restricting slop. No other bearing is this precise.

Note that these may not fit street wheels due to the larger flange; wheels without cores often have oversized bearing seats which may obstruct the inner flange. If in doubt, contact us or use the Tekton Lites.
