Most people know Seismic Speed Vents as the number one long distance pushing and pumping wheel, but did you know that they are also efficient downhill and freeride wheels?

The 73mm Seismic Speed Vent was first seen around July of 2008. Over the years it’s been available in an assortment of sizes and urethane formulae. The 73mm size, BlackOps urethane and Energy Conversion core make a great allrounder.
