Full Description / Key Features

Upgrade your gravity setup with the SPANK 369 Vibrocore™ Rim. Extensively tested at World Cup race paces by The Gravity Cartel WCDH team, this rim combines advanced metallurgy with unique geometry to withstand the harshest tracks on earth.

• Vibrocore™ Foam Core: The proprietary inner well core reduces the transmission of harmful vibration frequencies, decreasing hand fatigue for the rider, smoothing out suspension feedback, and significantly extending the fatigue life of the rim.
• Optimized Radial Compliance: A moderately low 19mm profile height maximizes vertical compliance to maintain structural traction over heavy chatter and square-edged bumps, while wide dimensions ensure absolute lateral stiffness and predictable cornering lines.
• Versatile 30.5mm Inner Width: Explicitly designed to support modern high-volume mountain bike tires from 2.0” to 2.6”. It accommodates plus-size tire setups without causing negative "squaring off" of the tire profile.
• Bead Bite™ Anti-Burp Technology: Advanced hookless tubeless design securely locks the tire bead in place. This enhances tubeless performance and ensures maximum tire security even at aggressive, ultra-low running pressures.
• Premium Dynamal Alloy Construction: Utilizing advanced aerospace-grade alloy, it features an Oohbah™ Inverted Inner Wall design and Sacred Geometry for industry-leading structural strength-to-weight ratios.
