About Seismic
Seismic patented an early longboard spring-truck design and advertised the original spring truck in TransWorld Skateboarding in September 1994.
The company produced its first wheel in the mid-1990s on Richter completes and later expanded high-performance wheels after taking over the 3DM line in 2004.
Seismic focuses on USA-made urethane wheels, Tekton bearings, Aeon/spring trucks, Lokton grip, and boards for racing, freeride, cruising, and related disciplines.
