TECHNOLOGIES

VIBROCORE

Vibrocore ™ is a patented, biodegradable and complex foam core that reduces vibrations. The low-density pressurized core performs a function similar to soft tissue within the bone, increasing the strength of the inner wall and absorbing vibrations. In addition, the torsional strength and durability of the rim are increased, which means a long service life with a significantly reduced weight. Vibrocore allows the design of modern rims with partially thinner wall thicknesses without having a negative effect on strength and resilience.

OohBah ™

The term OohBah describes Spank's unique rim profile, which, thanks to its special design, better dissipates power flows and thus avoids dents. Additionally, the wall can be adjusted at various points to make the rim lighter without sacrificing stability.

BeadBite

BeadBite creates a better seal between the rim chamber and the tire bead, preventing air from escaping no matter how much the tire moves. It also ensures that the tire bead is firmly anchored to the base of the rim and cannot slip.
