The tire that started the Road Tubeless movement enters its next generation with the Fusion 3. Road tubeless makes it possible to run lower pressure without pinch flats. A tire with lower pressure better conforms around imperfections in the road, limiting precious speed and energy loss. A higher pressure tire tends to bounce off imperfections causing a force away from the direction of motion. Triple rubber compound for fast rolling durability on straights and progressive grip on corners. Kevlar anti-puncture belt. 127 tpi casing. Designed for use with a tubeless compatible wheelset. 700c (622mm ISO). Color: Black. 302 grams.
