The AB1 Roller, beyond its modern design, ensures the preservation of the mechanical properties of the blank on which it is mounted, stabilizing the action along the blank’s flex axis as applied loads vary. Until now, with standard rollers on the market, the binding point often becomes misaligned—unlike the AB1 Roller—because the unique shape of the foot allows for a perfect fit along the entire curve of the blank, creating a seamless integration with the rod. The design perfection we’ve achieved with AB1 Rollers is primarily based on the presence of flexible feet that allow independent horizontal and vertical movement, separate from the roller’s main structure. This independence prevents any effect on the anchoring point where concurrent forces are applied. Additionally, this mechanism, besides reducing stress on the blank, supports its action during combat. Finally, the AB1 Roller is designed to support fishing with both nylon monofilament and braided lines.
