Catapult Effect
Volkl Tennis racquets with Catapult Effect have Catapult springs built into the frame at the 3 and 9 o’clock areas. These Catapult Effect springs give racquets more power and potentially more control even on off-center shots which gives them an expanded sweet spot.
The net result is that Volkl Tennis Catapult Effect models have a very plush, comfortable feel with amazing control along with the power players expect in this category of racquet. Catapult racquets are great for any level player looking for the most comfortable feel in that genre of racquet.
