On June 10, 2025, Diadem launched its innovative BluCore technology in the Diadem Warrior BluCore series of pickleball paddles, marking a significant advancement since the shift from wooden to composite paddles. BluCore uses a proprietary expanded polypropylene (EPP) core designed for durability, backed by a lifetime warranty against core failures like delamination and core crush. The Warrior BluCore series offers nine variants across three shapes and core thicknesses, catering to different player preferences for control, power, and sweet spot size.
Performance testing of two models, the Warrior BluCore Pro 14 and Max 16, revealed consistent dwell time and spin potential, with carbon fiber and kevlar faces providing bite despite a less gritty feel. The Pro 14 favored players seeking power and a longer handle for two-handed shots, while the Max 16, after adding weight tape for stability, offered a wider sweet spot and balanced play. Overall, the series suits experienced players looking for customizable paddle options with reliable, long-lasting performance.
