Cyclone is an attack bit built around a spiral: the tip is flat, but instead of a plain circular contact patch it carries a counter-clockwise star pattern cut into the plastic. Those grooves bite the stadium floor and drag the bey into aggressive circling from the moment it lands, which is how it gets to the X-Line and triggers Xtreme Dashes. The shaft above the tip is wider than usual, and that extra girth is why it holds together under launch stress better than most bits in its class. The friction that generates the aggression also burns spin quickly, so stamina is close to the bottom of the range.
Where Cyclone lands competitively is a bit awkward. It is easier to steer than Flat or Low Flat while producing broadly similar results, which makes it a pleasant bit to learn on but not one that wins events. Rush and Low Rush are the options serious attackers reach for instead.
Cyclone does show documented wear: repeated collisions with the X-Line can leave small dents in the spiral tip, so anyone using it regularly should expect to keep spares on hand.
