Introducing the all-new

Signature Series Alphas

Seismic tweaked the Alphas with sage advice from world-renowned racers Chase Hiller and Aaron Hampshire. Both are notorious threats on the track and know a thing or two about pushing wheels to their limit. We’re proud to add both of their Signature Model Alphas to our lineup!

Exclusive 74a Plum Defcon: Plush, velvety roll with strong edge hold, even on rough roads. Aggressive yet smooth slide with fast braking.

Chase was born and raised in the steeps of the Ozarks, so it’s fitting that the 75.5mm Alpha in 74a Plum Defcon is a technical downhill killer. Like Chase, this wheel lives and breathes STEEP, TIGHT CORNERS!

80.5mm Aaron Hampshire Pro
Hailing from Colorado, Aaron is no stranger to thin air and high speeds. The 80.5mm Alpha in 74a Plum Defcon is designed for reaching full HIGHWAY VELOCITY down those rough Rocky Mountain passes!
