The Reaver is a “go to” tire for gravel racing. It's faster lighter and even more durable than the venerable Rambler. A low-profile tread design uses diamond knurling to reduce rolling resistance and enhance grip in dusty or loose conditions. Paddle knobs arranged in sets of three provide extra bite under hard braking. The side knobs are spaced closely together and are staggered for consistent cornering performance. A sipe (groove) in each of the side knobs allows them to flex and conform to the terrain improving traction.Race-ready tread design intended to go fast on gravel and dirtRecommended for Pavement/asphalt dirt roads gravelTubeless ready tires provide the rider with many benefits: the ability to run lower air pressures which improves traction; lower rolling resistance when compared to a tube-type tire; and less chance of flatting because there is no tube Flat Protection Sidewall TPI 120 Color Black, Black/Tan, Tan Weight 430, 495, 509, 540 Defined Color Black, Tan ISO Width (mm) 40, 45 ISO Diameter 622 / Road / 29" keyword search performance gravel Tire Intended Use Gravel Tire Diameter 700c Tire Bead Folding Labeled Size 700 x 40, 700 x 45 Tire Type Tubeless Ready
