Fission Microbubble Technology produces an ultralight core with evenly distributed and imperceptible weight-reduction microbubbles. The ultralight core allows an even higher GYRO overmold density relative to the core, yet still remaining in the lighter weight classes..

This produces an entirely new type of lightweight disc never before seen in the sport, and beyond the capability of any other manufacturer. Weight distribution, stability, and durability of prior “bubble” discs are all improved upon by Fission. Skeptics of prior light or bubble plastics are in for a surprise, as Fission® brings advanced disc physics and true high-tech molding into the lightweight plastics arena.
