This professional player series dart barrel comes from the renowned Japanese brand DYNASTY, known for its superior quality and ownership satisfaction. This model is the first release from the A-FLOW's highest tier "OBSIDIAN LINE".
Maintaining the original concept, two types have been restructured in specs, outline, and cut configuration, evolving into a special edition that pursues presence, precision, and perfection suitable for the OBSIDIAN LINE. The grip center features the shining "Prism Link Cut".
Characterized by a three-dimensional grip feel created by the multifaceted structure, and a ring-linked design. Combining different-angled diamond shapes achieves a balance of moderate hooking and precise grip positioning. The unique holding sensation generated during the throw sharply connects to the player's feel.
The 51mm 22g model, based on the Riell, evolves into an aggressive specification that offers the pushing sensation and presence of a heavyweight barrel while enabling delicate release. It embodies both "inheritance" and "evolution."
Riell ST marks the dawn of the OBSIDIAN LINE by presenting distinct perfected forms.
