The Speedster Fat's minimal tread design and low-profile, honeycomb center tread reduce rolling resistance to a minimum. Large diamond-shaped side lugs pack into corners and gradually decrease in height toward the center for smooth transitions. Designed for hard terrain or asphalt, the Speedster is effortlessly fast in the dry and efficiently dissipates water in the wet.
