The Spike 369 Vibrocore rim is engineered for aggressive gravity and enduro riding delivering a unique blend of strength compliance and vibration damping. Designed with Spank’s innovative technologies the Spike 369 features a wide 30.5mm inner profile that supports a broad range of tire sizes providing optimal traction and control without compromising tire shape. Its Sacred Geometry hollow bead wall and Bead Bite tubeless interface improve lateral stiffness impact resistance and air retention—even under low pressure. The moderately low 19mm profile height enhances radial compliance for improved comfort and traction on rough terrain. What sets it apart is the integrated Vibrocore foam which reduces harmful vibrations improving ride feel and extending rim life. Backed by real-world testing with The Gravity Cartel WCDH team the Spike 369 Vibrocore rim is a top-tier choice for riders demanding performance durability and control at race pace.Sacred Geometry hollow bead wall design improves lateral and vertical strength. A wider bead wall effectively reduces pinch flats and increases impact resistance Moderately low 19mm profile height and wide width balances the benefits of radial compliance with high lateral stiffness and predictable handling Radial Compliance improves traction over bumps and chatter while reducing negative feedback to the rider; Performance and comfort are improved 30.5mm inner width is extremely versatile supporting wider tires without creating negative 'squaring off' of tire profiles Bead Bite hookless design enhances tubeless performance and tire security even at lower pressures Vibrocore inner well reduces the transmission of harmful vibration frequencies meaning less vibration for the suspension and rider also increasing the fatigue life of the rim
