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.
