Spank 350 Vibrocore Boost E-HG Rear Wheel 29 Inch 32-Hole 148 mm - black

Due to the low rim profile and the wide inner diameter, the Spank 350 wheels have high radial flex, which improves traction and comfort. At the same time, they have high lateral stiffness and high torsional strength - also thanks to the negative spoke holes with negative offset. The Spank 350 rims were combined in this wheel with high-quality e-bike specific Hex J-Type hubs made of steel.
The 350 Vibrocore wheels feature Vibrocore foam, which filters vibrations on the one hand, but is especially suitable for rough terrain and ensures high robustness. This also extends the lifespan of the wheels.

E-mountain bikes are no longer just a trend in Germany and Austria, but have now become an integral part of the sport. Therefore, it is all the more important to have specifically adapted parts that are designed for use with an e-motor and its power influences. Thus, the HEX hubs are now also available with freewheels made of steel.

Technologies of the Spank 359 Vibrocore wheels

Vibrocore
Vibrocore™ is a proprietary, biodegradable, complex foam core that reduces vibrations. The low-density pressurized core performs a similar function to the soft tissue inside bones, increasing the inner wall strength and absorbing vibrations. Furthermore, the torsional strength and durability of the rim are increased, which means 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, through special construction, better dissipates the occurring force flows and thus avoids dents. In addition, the wall can be adjusted at various points to construct the rim lighter without losing stability.

BeadBite
BeadBite creates an improved seal between the rim bed and tire bead, so no air can escape, no matter how much the tire moves. It also ensures that the tire bead is firmly anchored to the rim bed and cannot slip.
