Seismic Blastwaves Defcon


Rated 0 out of 5
(be the first to review)



Unlike previous wheels in the Seismic line, the Blast Wave has a slightly radiused outer lip for high grip with controlled sliding. It’s molded around the full version of our proprietary Energy Conversion core, making it astoundingly light for a wheel of this size – so much so that top racers use it for disciplines ranging from Tight Slalom all the way to technical Downhill. Truly a “blast” to ride, and destined to rewrite the book on the versatility of tall wheels.
