Seismic 82A Urchin

70mm tall x 44mm wide Urchin wheels with a 38mm running surface feature an offset bearing seat, a radiused outside edge, and a beveled inside edge. Each wheel weighs 5.0 oz and is sold in sets of four. Available in three proprietary formulas with finely-tuned durometer choices:

• Defcon™: Guinness WR speed for faster acceleration, easy and predictable in-slide feedback, extremely slow and consistent wear.
• 78A Mango (stoneground): Offers a super fast roll, smooth and predictable in-slide feedback, with a defined yet easy release.
• Premium Clear™: The best beautiful clear urethane in the world at 80A.
• Crystal Clear Blue: Smooth-rolling, fast, and grippy when fresh; sugary smooth sliding when broken in.
• Elixir™: Provides smooth, predictable slides (even on concrete), easy release and hookup, supreme control, and bright 'thane lines.
• 82A Red (stoneground): Ultra smooth and buttery with bright 'thane lines.

These versatile wheels are designed to hold lines at speed while allowing easy breakout for big slides. Now featuring a bigger bevel on the inside edge, stoneground running surfaces, and expanded formula options, they are better than ever for hucking standups into corners and slashing your way down a hill, across town, or through an alley.

The height and width are perfectly balanced for modern all-around riding, offering smooth, easy, comfortable, and predictable slide release, amazing in-slide feedback and control, and consistent wear. Molded around an advanced Mini-EC hub, these wheels preserve ample tire thickness while saving over half an ounce per wheel, stiffening the inside edge, and enhancing inside edge rebound. This results in better roll speed, more predictable handling, and improved slide control.
