THE OUSTER FROM CST WAS BUILT FOR THE MOUNTAINS. This tire lives and breathes singletrack. Tall, open center tread keeps the mud off your tires and grips hard while climbing. Aggressive side knobs dig into the loose soil and give you the confidence to rail your bicycle through the turns. The Ouster is available in wire or folding bead in 26% and 29% sizes. The folding bead versions feature dual-compound rubber and EPS (Exceptional Puncture Safety) puncture protection. Exceptional Puncture Safety (EPS)offers an added layer of proprietary rubberized poly-fiber material between the tread and the casing. The tight weave of this lightweight, puncture-resistant layer prevents foreign objects from penetrating the casing and damaging the tube.
