Ritchey's Tom Slick is the original gravel monster. With deep, grip-boosting VFA grooves and a tough Stronghold reinforced casing, these tires are what you want when the ride keeps going after the pavement ends. Stronghold reinforced casing resists cuts and punctures and allows for lower pressures without increased risk of pinch flats.
In 1984 Tom was the first to appropriate road tire technology for mountain bike tire design by introducing tread wear analysis, higher TPI and more compliant rubber compounds. Pioneering what he called Vector Force Analysis, he developed trail-specific tread patterns and technology for MTB tires. The result was the first ever rotation-specific tire, as well as the first front- and rear-specific treads. The newest mountain bike tires to the Ritchey line are no strangers to VFA; featuring a wider, reinforced casing to handle a more aggressive terrain, the Bite and Drive are the culmination of years of analysis for all mountain riding. Bite: front or rear, rotation-specific tread that bites into the terrain for excellent control in all conditions - VFA Tread Design - 7mm StrongHold bead-to-bead casing reinforcement (WCS) - Tubeless-ready (WCS) - WCS (120 TPI) or Comp (30TPI) levels - 795g (650b WCS)
Ritchey's signature mountain bike tread pattern for well over a decade, the Z-Max Evolution is the culmination of years of development and VFA design. Tread lugs are spaced wider and shortened for faster handling, reduced rolling resistance, and lighter weight. WCS version features dual compound and is tubeless-ready—softer sides enhance cornering while the firmer center section rolls faster and is more durable. - Tubeless Ready (WCS) - Weight: 586g (27.5 x 2.1") / 710g (27.5 x 2.25")
