Sprinting out of the last corner of a crit rewards a tire that rolls fast and holds its line, and the Eagle F1 SuperSport RS Tubeless Tire is a tubeless-ready road race tire that does both. Goodyear reports a 15 percent drop in rolling resistance at 72 pounds per square inch compared with the previous Eagle F1 SuperSport R. A non-overlapping double-layer casing keeps the overlap out of the contact patch so the tread flexes with less energy loss, and a reinforced shoulder adds lateral support when the bike leans over. What Our Gearhead(R) Experts Are Saying:"Wet descents in road races showed me this tire holds its line when the pavement is slick, because the UUHP compound, a silica-rich rubber blend, keeps its grip through the turn. I now carry more speed into wet corners, and the tire settles instead of skating."
