The Spank 350 Vibrocore rear wheel Boost
Due to the low rim profile and the wide inner diameter, the Spank 350 wheels have a high radial flex, which improves traction and comfort. At the same time, they have high lateral rigidity and high torsional strength - also thanks to the negative spoke bores with negative offset. The Spank 350 rims were combined with high-quality Hex J-Type hubs on this wheel
The 350 Vibrocore wheels have Vibrocore foam, which on the one hand filters vibrations, but is especially suitable for hard running in the wheel and ensures a high level of robustness. It also extends the life of the impellers.

Technologies used
In this chapter we explain the technologies that the manufacturer uses for this product.
Vibrocore
Vibrocore ™ is a proprietary, biodegradable, complex foam core that reduces vibrations. The pressurized, low-density core performs a similar function to the soft tissue inside the bone, increasing the inner wall thickness and absorbing vibrations. Furthermore, the torsional strength and durability of the rim are increased, which means a long service life with a remarkably low weight. Vibrocore enables modern rim designs with partially thinner wall thicknesses, without this having a negative effect on strength and resilience.
OohBah ™
The term OohBah describes Spank's exclusive rim profile, which, thanks to its special design, better dissipates the force flows and thus avoids dents. In addition, the wall can be adjusted in various places to make the rim easier to construct without sacrificing stability.
BeadBite
BeadBite creates an improved seal between the rim bed and the tire bead, so that no air can escape, no matter how much the tire moves. It also ensures that the tire bead is firmly anchored to the rim base and cannot slip.
