Fission Delirium (OTB Open 2026)

Fission Delirium – 2026 OTB Open – Overstable Distance Driver
The 2026 OTB Open Fission Delirium takes Axiom’s fastest, most overstable distance driver and pairs it with a striking alien‑themed design from Green C Studio. Built for players who rely on power‑driven distance and wind‑fighting stability, the Delirium delivers uncompromising performance at maximum speed.

The Delirium is a high speed overstable distance driver.

Make the competition feel delirious with the Axiom Neutron Delirium! The Neutron Delirium is an overstable distance driver designed for maximum speed and very overstable flights. The Delirium joins the Tantrum and Excite distance drivers as the overstable 24.5 MM Distance Driver making its debut in Neutron Plastic. Fans of the MVP Dimension will find a kindred spirit in the Delirium due to its capacity for high speed throws with minimal turn, even in high wind situations. Take the wind head-on with maximum distance drives from Axiom Discs Neutron Delirium Distance Driver!

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 — 145g to 175g in the Photon.

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.
