Precision engineered shafts are critical to the proper flight of your darts. The Viper Aluminum Spinster Shafts provide a multitude of great features to bring your dart game to the next level. The key feature is the rotating top. This allows flights to rotate freely while the dart is still in the board. The flights can spin out of the way of incoming darts which would normally cause deflection. When you reduce dart deflection, you can achieve tighter shot groupings and higher scores. These shafts are constructed from tough, lightweight aluminum. Using this material is a mark of quality in dart shafts as they will stand up to tough wear and tear without adding unnecessary weight to your darts, adversely affecting their flight. With a locking hole featured on these shafts, you can use extra leverage to tighten them to the barrel, optimizing your dart's trajectory by minimizing movement. Once locked into place, you won't find yourself retightening after just a throw or two. The medium size comfortably spaces the flight from the barrel, further improving the flight path. Includes three short shafts.
