The HEX gravel tire combines the elements required for those seeking a performance option that doesn't sacrifice traction. A novel tread design features hexagonal blocks that allow a three-way flex pattern to add suppleness to the casing, allowing the tire to conform to varied surface conditions for consistent handling. This provides both driving and braking traction for confident handling. Pioneered on the SES Race Day road tire, the HEX uses a nano-particle-enhanced rubber compound that reduces rolling resistance, improves traction, and extends tread wear. Combined with a supple casing, the HEX delivers a supple ride quality and rolling efficiency. The tubeless ready tires are available in 40c and 44c sizes.
