For 2018 Spank presents a revolutionary new development: the Spike 350 Vibrocore wheels.
Due to the low rim profile and the wide inner diameter, the rim has high radial flex, which improves traction and comfort. At the same time it has high lateral stiffness and high torsional strength - also thanks to the negative spoke holes with negative offset. The high-quality spike hubs have sealed bearings and a 48-tooth grid (rear).
The Vibrocore core dampens vibrations, increases rim stability and ensures that the rim returns to its original condition quickly and in a controlled manner, despite higher flex. At the same time, the Vibrocore core increases the service life of the rim.
