The Alkali RPD Quantum Roller Hockey Puck brings consistency to every shift, thanks to its IDS construction and smooth-gliding runner system. Its harder durometer and stiffer feel gives players reliable accuracy on passes, shots, and quick stickhandling transitions. A center-weighted design minimizes unwanted rolling, ensuring smooth gameplay from puck drop to the final buzzer. Each puck also features replaceable glide pins, letting you refresh performance at a fraction of the cost of buying a new puck.
