70mm Seismic Urchin Wheels


  • $ 4795

An extremely versatile wheel, with height and width perfectly balanced for modern all-around riding.  Enough grip to hit corners with speed, but easy breakout for big slides.

Poured in 82A red Elixir freeride formula for smooth, predictable slides and bright ’thane lines.

Molded around our advanced Mini-EC hub – preserves ample tire thickness while saving over ½-ounce per wheel, stiffening the inside edge, and super-charging inside edge rebound.  Translation: Better roll speed, more predictable handling, and better slide control!
