Starting with the 2014 Organix racquets, Volkl introduces a new Pin System in their Bio Sensor handles. These pins are made of a material called V-Sponse" which has exceptional dampening properties.
There are three different types of pins, each with unique benefits to the target playing audience. The RED PIN is the softest and is great for recreational players looking for maximum comfort. The YELLOW PIN is medium firm and is great for intermediates who want a comfortable but slightly firmer feel. Finally, the BLACK PIN is for advanced players who want maximum feedback.
