SPANK 369 Vibrocore 29" Rear Wheel | 32H Hex Boost 12x148mm (Excludes Freehub)

The SPANK 369 Vibrocore™ 29-inch Rear Wheel is an elite ASTM 5 rated mountain bike wheel engineered for Trail, Enduro, Downhill, and Freeride. Featuring a low-profile 19mm rim height for unmatched radial compliance, a wide 30.5mm inner width, and a high-engagement HEX J-Type Boost Hub, this rear wheel delivers predictable handling and maximum traction over harsh trail chatter.

Key Features & Benefits

• Vibrocore™ Vibration Dampening: Features a proprietary foam core inside the inner rim well that dampens harmful high-frequency vibrations, reducing rider fatigue and extending the fatigue life of your rim and suspension.
• Radial Compliance & Lateral Stiffness: The optimized 19mm profile height balances vertical flex to boost traction over bumps while maintaining high lateral stiffness for sharp, aggressive cornering.
• Versatile 30.5mm Inner Width: Generous internal rim width perfectly supports mountain bike tires from 2.0” to 2.6”, preventing tire profile squaring and improving cornering security.
• Bead Bite™ Tubeless Technology: Patented tubeless hooks greatly enhance tubeless tire security and prevent burping, even when running extra-low tire pressures.
• Superboost Compatible: The 150/157mm configurations are natively compatible with Superboost bike frames, including Pivot, Evil, Devinci, and more.
• E-Bike Ready: Recommended for high-torque E-MTB applications when paired with a heavy-duty SPANK HEX DRIVE steel freehub body (sold separately).
