Seismic Tantrum


The Tantrum is Seismic’s freeride wheel. With versions in both their buttery Elixir formula and high-speed Defcon 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 XT 7 Ball Bearings

If you'd had some Seismic bearings before, you know roughly what to expect here; 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. However, these new XT Tektons have gone through a redesign, with thicker casings to reduce any flexing and make them even stronger and faster than ever.

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.
