Spank Spank 369 Vibrocore HG Rear Wheel, 29", 32H, 150/157mm - black

Spank 369:

The Sacred Geometry hollow bead design improves lateral and vertical strength. The wider bead wall effectively reduces pinch flats. It also increases impact resistance.

The moderately low profile height of 19 mm and the large width provide a balance between the benefits of radial compliance and high lateral stiffness, as well as predictable handling.

The radial compliance improves traction on bumps and road irregularities while simultaneously reducing negative feedback to the rider. Performance and comfort are enhanced.

Vibrocore™ internal bed reduces the transmission of harmful vibration frequencies, resulting in less vibration for the suspension and the rider, and increases the lifespan of the rim.

The internal width of 30.5 mm is extremely versatile and fits tyres from 2.0“ to 2.6“ and even allows the use of + size tyres without negatively deforming the tyre profile.

The tubeless-ready Bead Bite design enhances tubeless performance and tyre security, even at lower pressures.

Vibrocore

Vibrocore™ is a proprietary, biodegradable, complex foam core that reduces vibrations. The low-density pressurised core serves a similar function to the soft tissue inside bones, increasing the inner wall thickness and absorbing vibrations. Furthermore, it increases the torsional strength and durability of the rim, resulting in a high lifespan at a remarkably low weight. Vibrocore enables modern rim designs with partially thinner wall thicknesses without negatively affecting strength and load capacity.

OohBah

The term OohBah describes Spank's exclusive rim profile, which better directs the occurring force flows through special construction, thus avoiding dents. In addition, the wall can be adjusted at various points to construct the rim lighter without sacrificing stability.

BeadBite

BeadBite creates an improved seal between the rim bed and tyre bead, preventing air from escaping, no matter how much the tyre moves. It also ensures that the tyre bead is firmly anchored to the rim bed and cannot slip.
