Want to go fast or far on some of the nicest urethane on the market, Seismic Alpha wheels bring technology and performance together in a line of wheels. Alpha's are named after the Greek letter “alpha” (α), representing rotational acceleration.
The Seismic Alpha wheel is a perfect balance of optimal properties for modern competitive racing, including size and momentum for speed, finely-tuned width and supremely supported edges for smooth and predictable handling in corners and some of the fastest urethane that the skateboard industry has ever seen.
The Alpha’s stout S-shaped edge profile optimizes lip support, maximizes traction under extreme G’s, and ensures predictable slide initiation and hookup. Integrates Seismic's Fusion Core that is formed from 85D fiber-reinforced thermoplastic, at 46 mm tall x 44 mm wide, it is the largest and most supportive hub ever seen in a wheel this size.
Perfect wheel for downhill, long-distance pushing or carving your favourite trail, with each of the different flavours of urethane offering a way to fine tune your ride
