A unique string offering incredible spin with surprising playability Volkl Cyclone 130 features a highly geometric gear shape which combines with copolyester construction The multisided shape features significant ridges which help to really bite the ball and result in the ability to generate tremendous amounts of spin As with many shaped strings Cyclone uses a block copolyester construction providing a combination of different properties of unique materials The advantage to this construction is that every aspect of performance in a string can be tuned by altering the block associated with it The overall effect is that this string offers enhanced ball speed improved control and most importantly incredible spin as compared to typical polyester strings We found that this string performed best from the baseline for hard hitting heavy spin players but still provides enough feel for the occasional trip to the netConstruction Monofilament CopolyesterColor BlackGauge 130mmLength 660 200m
